This family includes the VinK acyltransferase. VinK transfers a dipeptide group between two ACPs, VinL and VinP1LdACP, in vicenistatin biosynthesis [1]. This entry represents the small C-terminal domain [1]. VinK has two conserved catalytic residues, Ser-106 and His-216, at the interface between the large domain and small domain [1].
