The N-isopropylammelide isopropylaminohydrolase from Pseudomonas sp. strain ADP, AtzC, provides the third hydrolytic step in the mineralization of s-triazine herbicides, such as atrazine. We obtained the X-ray crystal structure of AtzC at 1.84 Å with a weak inhibitor bound in the active site and then used a combination of in silico docking and site-directed mutagenesis to understand the interactions between AtzC and its substrate, isopropylammelide. The substitution of an active site histidine…

An unexpected vestigial protein complex reveals the evolutionary origins of an s-triazine catabolic enzyme
It is proposed that AtzEG was likely recruited into the cyanuric acid–mineralizing pathway from an ancestral glutamine transamidosome that required protein–protein interactions to enforce the exclusion of solvent from the transamidation reaction.
The evolving story of AtzT, a periplasmic binding protein
The structure of AtzT, which is thought to be involved in atrazine uptake in bacteria, was solved by SAD phasing using an ethylmercury phosphate derivative to replace guanine with 2-hydroxyatrazine.
Structural and biochemical characterization of the biuret hydrolase (BiuH) from the cyanuric acid catabolism pathway of Rhizobium leguminasorum bv. viciae 3841
The structure of the inactive Cys175Ser BiuH variant with substrate bound in the active site revealed that an active site cysteine (Cys175), aspartic acid (Asp36) and lysine (Lys142) form a catalytic triad, which is consistent with biochemical studies ofBiuH variants.


X-ray Structure and Mutational Analysis of the Atrazine Chlorohydrolase TrzN*
Atrazine chlorohydrolase, TrzN (triazine hydrolase or atrazine chlorohydrolase 2), initiates bacterial metabolism of the herbicide atrazine by hydrolytic displacement of a chlorine substituent from
Three-dimensional structure and catalytic mechanism of cytosine deaminase.
Large inverse solvent isotope effects were obtained on k( cat) and k(cat)/K(m), consistent with the formation of a low-barrier hydrogen bond during the conversion of cytosine to uracil, and a chemical mechanism for substrate deamination by CDA was proposed.
X-Ray Structure of the Amidase Domain of AtzF, the Allophanate Hydrolase from the Cyanuric Acid-Mineralizing Multienzyme Complex
Interestingly, it is shown that AtzF forms a large, ca.
Purification, Substrate Range, and Metal Center of AtzC: the N-Isopropylammelide Aminohydrolase Involved in Bacterial Atrazine Metabolism
The data suggest that AtzC has a catalytically essential, five-coordinate Zn(II) metal center in the active site and specifically catalyzes the hydrolysis of intermediates generated during the metabolism of s-triazine herbicides.
Structural and catalytic diversity within the amidohydrolase superfamily.
The amidohydrolase superfamily comprises a remarkable set of enzymes that catalyze the hydrolysis of a wide range of substrates bearing amide or ester functional groups at carbon and phosphorus
Cyanuric acid hydrolase: evolutionary innovation by structural concatenation
The first X‐ray structure for the cyanuric acid hydrolase, AtzD, is reported, which is a novel fold that likely evolved via the concatenation of monomers of the trimeric YjgF superfamily and the acquisition of a metal binding site.
Hydroxyatrazine N-Ethylaminohydrolase (AtzB): an Amidohydrolase Superfamily Enzyme Catalyzing Deamination and Dechlorination
An intensive in vitro investigation into the substrate specificity of AtzB revealed that 20 of the 51 compounds tested were substrates for Atz B; this allowed for the identification of specific substrate structural features required for catalysis.
The structure of the hexameric atrazine chlorohydrolase
A crystal structure of the full hexameric form of AtzA, which is less well adapted to its physiological role than the alternative metal-dependent atrazine chlorohydrolase (TrzN), with a substrate-binding pocket that is under considerable strain and for which the substrate is a poor fit.
Crystal structure of D-aminoacylase from Alcaligenes faecalis DA1. A novel subset of amidohydrolases and insights into the enzyme mechanism.
D-aminoacylase defines a novel subset and is a mononuclear zinc metalloenzyme but containing a binuclear active site, and is the first example of the metal ion coordination by a cysteine residue in the superfamily.
Crystal Structure of Yeast Cytosine Deaminase
The enzyme shares similar active-site architecture to cytidine deaminases and an unusually high structural homology to 5-aminoimidazole-4-carboxamide-ribonucleotide transformylase and thereby may define a new superfamily.
