Structure-based prediction of modifications in glutarylamidase to allow single-step enzymatic production of 7-aminocephalosporanic acid from cephalosporin C
glutaryl-7-aminocephalosporanic-acid acylase / glutaryl-7-aminocephalosporanic-acid acylase activity / hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in linear amides / antibiotic biosynthetic process / periplasmic space / response to antibiotic / metal ion binding 類似検索 - 分子機能
CATALYTICLLY ACTIVE CEPHALOSPORIN ACYLASE IS FORMED BY A TWO-STEP AUTOCATALYTIC PROCESS FROM THE ...CATALYTICLLY ACTIVE CEPHALOSPORIN ACYLASE IS FORMED BY A TWO-STEP AUTOCATALYTIC PROCESS FROM THE INACTIVE INTACT PRECURSOR. IN THE FIRST STEP THE PRECURSOR POLYPEPTIDE CHAIN IS CLEAVED INTO A SHORT (A1-A170) AND A LONG CHAIN (B1-B522). IN THE SECOND STEP THE SPACER PEPTIDE A161-A170 IS REMOVED. THE HETERO-DIMER IS NUMBERED HERE AS RESIDUES A8-A160 AND B1-B522.
