(B) The proposed biosynthetic routes and main end-product of each biosynthetic pathway. Adenylation domains and their predicted substrates are given in blue. C, condensation domain; PCP, peptidyl carrier protein; E, epimerase domain; R, reductase domain; KR, ketoreductase domain; ACP, acyl carrier protein.
