CC -!- FUNCTION: Component of the p-aminobenzoyl-glutamate hydrolase
CC multicomponent enzyme system which catalyzes the cleavage of p-
CC aminobenzoyl-glutamate (PABA-GLU) to form p-aminobenzoate (PABA) and
CC glutamate. AbgAB does not degrade dipeptides and the physiological role
CC of abgABT should be clarified. {ECO:0000269|PubMed:17307853,
CC ECO:0000269|PubMed:20190044}.
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000269|PubMed:20190044};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=60 uM for PABA-GLU (at pH 8.5) {ECO:0000269|PubMed:20190044};
CC -!- SUBUNIT: Forms a heterodimer with AbgB. {ECO:0000269|PubMed:20190044}.
CC -!- INTERACTION:
CC P77357; P76052: abgB; NbExp=2; IntAct=EBI-9155452, EBI-1123629;
CC -!- INDUCTION: Could be transcriptionally regulated by AbgR.
CC {ECO:0000269|PubMed:9829935}.
CC -!- SIMILARITY: Belongs to the peptidase M20 family. {ECO:0000305}.
