'''Structure of acetylcitrulline deacetylase complexed with one Co'''

== Function ==

[https://www.uniprot.org/uniprot/ACDAS_XANCP ACDAS_XANCP] Catalyzes the deacetylation of N-acetyl-L-citrulline to produce L-citrulline. This is a step in an alternative arginine biosynthesis pathway (PubMed:16585758, PubMed:16511126). Is also able to catalyze the deacetylation of N-acetylornithine in vitro, with almost equal velocity. However, this reaction may be not relevant in vivo since Xanthomonas does not possess the canonical argF gene and cannot convert ornithine to citrulline via ArgF' (PubMed:16585758).<ref>PMID:16511126</ref> <ref>PMID:16585758</ref>

The structure of a novel acetylcitrulline deacetylase from the plant pathogen Xanthomonas campestris has been solved by multiple-wavelength anomalous dispersion (MAD) using crystals grown from selenomethionine-substituted protein and refined at 1.75 A resolution. The asymmetric unit of the crystal contains one monomer consisting of two domains, a catalytic domain and a dimerization domain. The catalytic domain is able to bind a single Co(II) ion at the active site with no change in conformation. The dimerization domain forms an interface between two monomers related by a crystallographic two-fold symmetry axis. The interface is maintained by hydrophobic interactions between helices and hydrogen bonding between two beta strands that form a continuous beta sheet across the dimer interface. Because the dimers are also related by two-fold crystallographic axes, they pack together across the crystal via the dimerization domain, suggesting that higher order oligomers may form in solution. The polypeptide fold of the monomer is similar to the fold of Pseudomonas sp. carboxypeptidase G2 and Neisseria meningitidis succinyl diaminopimelate desuccinylase. Structural comparison among these enzymes allowed modeling of substrate binding and suggests a possible catalytic mechanism, in which Glu130 functions as a bifunctional general acid-base catalyst and the metal ion polarizes the carbonyl of the acetyl group.
