    Protein Summary

    The LBUL1103 (patC) gene from Lactobacillus delbrueckii bulgaricus atcc baa-365 encodes a PLP-dependent aminotransferase (PF00155, COG1168, EC 2.6.1.-). The structure contains two domains and adopts a PLP-dependent transferase-like fold with significant structural similarity to cystalysins (PDB ids 1C7N, 1D2F), aspartate aminotransferases (PDB ids 1J32, 1O4S) and other aminotransferases of varying specificities. A search with PSI-BLAST indicates that the protein is likely as a beta-cystathionase. Previous work has shown that this enzyme can have a dual role, functioning both as a beta-cystathionase and as a modulator of maltose gene expression [Ref].
