We suppose that there are some enzymes responsible for converting intermediate JI - 20A to 3 ' , 4 ' - bisdehydroxylated final product gentamicin C ( 1a ) , while phosphorylation of 3 ' - OH is possibly the first step for C - 3 ' dehydroxylation .
 Chemical: JI - 20A; Chemical: gentamicin C; Chemical: 3 ' - OH
