'''CRYSTAL STRUCTURE ANALYSIS OF N-CARBAMoYL-D-AMINO-ACID AMIDOHYDROLASE'''
== Function ==
 
[https://www.uniprot.org/uniprot/DCAS_RHIRD DCAS_RHIRD] The enzyme catalyzes the hydrolysis of N-carbamoyl-D-amino acids to the corresponding which are useful intermediates in the preparation of beta-lactam antibiotics. Industrial production of beta-lactam antibiotics is now being developed using this enzyme.

==Overview==
[[Image:Consurf_key_small.gif|200px|right]]
The N-carbamoyl-D-amino-acid amidohydrolase (D-NCAase) is used on an industrial scale for the production of D-amino acids. The crystal structure of D-NCAase was solved by multiple isomorphous replacement with anomalous scattering using xenon and gold derivatives, and refined to 1.95 A resolution, to an R-factor of 18.6 %. The crystal structure shows a four-layer alpha/beta fold with two six-stranded beta sheets packed on either side by two alpha helices. One exterior layer faces the solvent, whereas the other one is buried and involved in the tight intersubunit contacts. A long C-terminal fragment extends from a monomer to a site near a dyad axis, and associates with another monomer to form a small and hydrophobic cavity, where a xenon atom can bind. Site-directed mutagenesis of His129, His144 and His215 revealed strict geometric requirements of these conserved residues to maintain a stable conformation of a putative catalytic cleft. A region located within this cleft involving Cys172, Glu47, and Lys127 is proposed for D-NCAase catalysis and is similar to the Cys-Asp-Lys site of N-carbamoylsarcosine amidohydrolase. The homologous active-site framework of these enzymes with distinct structures suggests convergent evolution of a common catalytic mechanism.
