CC   -!- FUNCTION: Inactivates the type B streptogramin antibiotics by
CC       linearizing the lactone ring at the ester linkage, generating a free
CC       phenylglycine carboxylate and converting the threonyl moiety into 2-
CC       amino-butenoic acid. {ECO:0000255|HAMAP-Rule:MF_01282}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01282};
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01282}.
CC   -!- SIMILARITY: Belongs to the Vgb family. {ECO:0000255|HAMAP-
CC       Rule:MF_01282}.
