Conversion of trachylobanic acid into novel pentacyclic analogues of gibberellins by Gibberella fujikuroi, mutant B1-41a
Abstract
12,16-Cyclogibborellins A9 and A12 have been isolated from the microbiological transformation of trachylobanic acid by Gibberella fujikuroi, mutant B1-41a, thus providing a notable example of the non-specificity of enzymes, catalysing the biosynthesis of fungal gibberellins; the 12,16-cyclogibberellin A9 retains gibberellin-like biological activity.
