I-TevI, a member of the GIY-YIG family of homing endonucleases, consists of an N-terminal catalytic domain and a C-terminal DNA-binding domain joined by a flexible linker. The GIY-YIG motif is in the N-terminal domain of I-TevI, which corresponds to a phylogenetically widespread catalytic cartridge that is often associated with mobile genetic elements. The crystal structure of the catalytic domain of I-TevI, the first of any GIY-YIG endonuclease, reveals a novel α/β-fold with a central three…

Distance determination by GIY-YIG intron endonucleases: discrimination between repression and cleavage functions
TLDR
I-TevI zinc finger mutants cleave the operator more efficiently than the homing site, the converse of wild-type protein, consistent with the zinc finger acting as a measuring device, directing efficient cleavage of the honing site to promote intron mobility, while reducing cleavage at the operator to ensure transcriptional autorepression and phage viability.
Folding, DNA recognition, and function of GIY-YIG endonucleases: crystal structures of R.Eco29kI.
TLDR
The structure of the GIY-YIG restriction endonuclease R.Eco29kI has been solved both alone and bound to its target site and illustrates how the GIy-Yig scaffold has been adapted for the highly specific recognition of a DNA restriction site, in contrast to nonspecific DNA cleavage by GIY/YIG domains in homing endonucleases or structure-specific cleavageBy DNA repair enzymes such as UvrC.
Amino Acid Residues in the GIY-YIG Endonuclease II of Phage T4 Affecting Sequence Recognition and Binding as Well as Catalysis
ABSTRACT Phage T4 endonuclease II (EndoII), a GIY-YIG endonuclease lacking a carboxy-terminal DNA-binding domain, was subjected to site-directed mutagenesis to investigate roles of individual amino
Structure of bacteriophage T4 endonuclease II mutant E118A, a tetrameric GIY-YIG enzyme.
TLDR
The scarcity of potential nucleic acid binding residues between the active sites indicates that EndoII may bind its substrate inefficiently across the two sites in the dimer, offering a plausible explanation for the catalytic preponderance of single-strand nicks.
F-CphI represents a new homing endonuclease family using the Endo VII catalytic motif
TLDR
Based on the unique conserved residues, it is proposed that F-CphI represents a new homing endonuclease family, which was named the DHHRN family and could be used to predict the functions of many previously unknown proteins.
Endonuclease II - a GIY-YIG enzyme of bacteriophage T4
TLDR
The scarcity of potential nucleic acid binding residues between the active sites indicates that EndoII may bind its substrate inefficiently across the two sites in the dimer, offering a plausible explanation for the catalytic preponderance of single-strand nicks.
Homing Endonuclease I-TevI: An Atypical Zinc Finger with a Novel Function
I-TevI is a site-specific, sequence-tolerant homing endonuclease encoded by the td intron of bacteriophage T4. The enzyme consists of an N-terminal catalytic domain and a C-terminal DNA-binding
Oligomeric structure diversity within the GIY-YIG nuclease family.
TLDR
Experimental evidence is provided that Eco29kI monomers dimerize on a single cognate DNA molecule forming the catalytically active complex, which may have implications for the function of homing endonucleases and other enzymes of the GIY-YIG family.
Role of the interdomain linker in distance determination for remote cleavage by homing endonuclease I-TevI.
TLDR
First, the linker DI region has a role in I-TevI cleavage activity, as evident from DT mutants that display a phenotype similar to that of the zinc-finger mutants in their selection of a cleavage site.
Biochemical and mutagenic analysis of I-CreII reveals distinct but important roles for both the H-N-H and GIY-YIG motifs
TLDR
It is shown that I-CreII can bind DNA without an added metal ion, and that it binds as a monomer, akin to GIY-YIG enzymes, and the data indicate that only the H-N-H motif has retained catalytic ability.

Configuration of the catalytic GIY-YIG domain of intron endonuclease I-TevI: coincidence of computational and molecular findings.
TLDR
The N-terminal catalytic domain corresponds precisely to the GIY-YIG module defined by sequence comparisons of 57 proteins including more than 30 newly reported members of the family, raising the possibility that this region may adopt an alternate conformation upon DNA binding.
Two-domain structure of the td intron-encoded endonuclease I-TevI correlates with the two-domain configuration of the homing site.
TLDR
Limited proteolysis experiments indicate that I-TevI consists of two domains that behave as discrete physical entities as judged by a number of functional and structural criteria.
Three-dimensional modeling of the I-TevI homing endonuclease catalytic domain, a GIY-YIG superfamily member, using NMR restraints and Monte Carlo dynamics.
TLDR
The subsequently elaborated full atomic model of the I-TevI CD allows the available experimental data to be put into a structural context and suggests that the GIY-YIG domain may dimerize in order to bring together the conserved residues of the active site.
Zinc finger as distance determinant in the flexible linker of intron endonuclease I-TevI
TLDR
Models are presented for the novel function of the zinc finger, as a molecular constraint, whereby intramolecular protein–protein interactions position the catalytic domain by “catalytic clamp” and/or “linker-organizer” mechanisms.
Intertwined structure of the DNA‐binding domain of intron endonuclease I‐TevI with its substrate
TLDR
The multiple base‐specific interactions over a long segment of the substrate are consistent with the observed high site specificity in spite of sequence tolerance, while the modular composition of the domain is pertinent to the evolution of homing endonucleases.
The structure of I-Crel, a Group I intron-encoded homing endonuclease
TLDR
The structure of I-Crel provides the first view of a protein encoded by a gene within an intron and the conserved LAGLIDADG motif, found in many mobile intron endonucleases, maturases and inteins, forms a novel helical interface and contributes essential residues to the active site.

TLDR
The results suggest that each endonuclease has independently evolved the ability to distinguish intron-containing from intronless alleles while maintaining the same conserved recognition sequence centered on DNA-encoding active site residues of TS.
The td intron endonuclease I‐TevI makes extensive sequence‐tolerant contacts across the minor groove of its DNA target.
TLDR
Genetic and physical studies indicate that the enzyme makes extensive contacts with its DNA substrate over at least three helical turns and around the circumference of the helix, providing a basis for understanding how I‐TevI recognizes T‐even phage DNA, which is heavily modified in the major groove.
Chemical mechanism of DNA cleavage by the homing endonuclease I-PpoI.
TLDR
I-PpoI appears to be unique among known restriction endonucleases and homing endonuclease in its use of a histidine residue to activate the attacking water molecule for in-line displacement of the 3'-leaving group.
Intron‐encoded endonuclease I‐TevI binds as a monomer to effect sequential cleavage via conformational changes in the td homing site.
TLDR
A model, wherein I‐TevI acts as a hinged monomer to induce a distortion that widens the minor groove, facilitating access to the top‐strand cleavage site, is proposed, compatible with both unmodified DNA and glucosylated hydroxymethylcytosine‐containing DNA.
