Predicted sites of action of the A47934-modifying enzymes. The sites of A47934 modification as predicted by the annotation of the sequence data are indicated. StaF, StaG, StaH, and StaJ crosslink the indicated amino acids, while StaI and StaK catalyze halogenations. The predicted sulfonylation action of StaL is unique to A47934. StaM or StaR may be responsible for hydroxylation of Tyr at position 6.
