10673442 Bompard-Gilles C, Villeret V, Davies GJ, Fanuel L, Joris B, Frere JM, Van Beeumen J: A new variant of the Ntn hydrolase fold revealed by the crystal structure of L-aminopeptidase D-ala-esterase/amidase from Ochrobactrum anthropi. Structure. 2000 Feb 15;8(2):153-62.

BACKGROUND: The L-aminopeptidase D-Ala-esterase/amidase from Ochrobactrum anthropi (DmpA) releases the N-terminal L and/or D-Ala residues from peptide substrates.

Here, we define a novel DOM-fold as a consensus structure of the domains in DmpA (L-aminopeptidase D-Ala-esterase/amidase), OAT (ornithine acetyltransferase), and MocoBD (molybdenum cofactor-binding domain), and discuss possible evolutionary scenarios of its origin.

Ochrobactrum anthropi possesses an L-aminopeptidase (DmpA) also able to act as a D-amidase/D-esterase.

However, differences in the connectivity reveal that OATs belong to a structural family different from that of other structurally characterized Ntn enzymes, with one exception: unexpectedly, the alphabetabetaalpha sandwich of ORF6 (where ORF stands for open reading frame) displays the same fold as an DmpA (L-aminopeptidase D-ala-esterase/amidase from Ochrobactrum anthropi), and so the OATs and DmpA form a new structural subfamily of Ntn enzymes.

In this work, the L-aminopeptidase-D-amidase/esterase (DmpA) from Ochrobactrum anthropi LMG7991 is compared to two closely related beta-peptidyl aminopeptidases (BapA), which originate from Sphingosinicella strains, and to microsomal leucine aminopeptidase (LAP) as a reference.

We have previously shown that the beta-aminopeptidases BapA from Sphingosinicella xenopeptidilytica and DmpA from Ochrobactrum anthropi can catalyze reactions with non-natural beta (3)-peptides and beta (3)-amino acid amides.

The second enzyme, DmpA, exhibits a similar substrate profile when tested on p-nitroanilide derivatives of glycine and L/D-alanine, but the amounts produced by the Ochrobactrum strain were not sufficient to allow complete purification.
