Molecular basis of transmembrane signalling by sensory rhodopsin II–transducer complex
Microbial rhodopsins, which constitute a family of seven-helix membrane proteins with retinal as a prosthetic group, are distributed throughout the Bacteria, Archaea and Eukaryota. This family ofExpand
Structure of the N6-adenine DNA methyltransferase M•TaqI in complex with DNA and a cofactor analog
The 2.0 Å crystal structure of the N6-adenine DNA methyltransferase M•TaqI in complex with specific DNA and a nonreactive cofactor analog reveals a previously unrecognized stabilization of theExpand
The pre-hydrolysis state of p21(ras) in complex with GTP: new insights into the role of water molecules in the GTP hydrolysis reaction of ras-like proteins.
BACKGROUND In numerous biological events the hydrolysis of guanine triphosphate (GTP) is a trigger to switch from the active to the inactive protein form. In spite of the availability of severalExpand
Crystal structure of the GAP domain of Gyp1p: first insights into interaction with Ypt/Rab proteins
We present the 1.9 Å resolution crystal structure of the catalytic domain of Gyp1p, a specific GTPase activating protein (GAP) for Ypt proteins, the yeast homologues of Rab proteins, which areExpand
Vps9, Rabex-5 and DSS4: proteins with weak but distinct nucleotide-exchange activities for Rab proteins.
The activities of three Rab-specific factors with GDP/GTP exchange activity, Vps9p, Rabex-5 and DSS4, with their cognate GTPases, Ypt51p, Rab5 and Ypt1p, have been analysed quantitatively. InExpand
Crystal structures of bovine chymotrypsin and trypsin complexed to the inhibitor domain of alzheimer's amyloid β‐protein precursor (APPI) and basic pancreatic trypsin inhibitor (BPTI): Engineering of
The crystal structures of the inhibitor domain of Alzheimer's amyloid β‐protein precursor (APPI) complexed to bovine chymotrypsin (C‐APPI) and trypsin (T‐APPI) and basic pancreatic trypsin inhibitorExpand
Time-resolved FTIR studies of the GTPase reaction of H-ras p21 reveal a key role for the beta-phosphate.
FTIR difference spectroscopy has been established as a new tool to study the GTPase reaction of H-ras p21 (Ras) in a time-resolved mode at atomic resolution without crystallization. The phosphateExpand
Characterization of the ternary complex between Rab7, REP-1 and Rab geranylgeranyl transferase.
Geranylgeranylation is a post-translational modification of Rab GTPases that enables them to associate reversibly with intracellular membranes. Geranylgeranylation of Rab proteins is critical forExpand
The crystal structure of human PAPS synthetase 1 reveals asymmetry in substrate binding.
The high energy sulfate donor 3'-phosphoadenosine-5-phosphosulfate (PAPS) is used for sulfate conjugation of extracellular matrix, hormones and drugs. Human PAPS synthetase 1 catalyzes two subsequentExpand
Three-dimensional structures and properties of a transforming and a nontransforming glycine-12 mutant of p21H-ras.
The three-dimensional structures and biochemical properties of two mutants of the G-domain (residues 1-166) of p21H-ras, p21 (G12D) and p21 (G12P), have been determined in the triphosphate-bound formExpand
