Abstract:
The brefeldin A (BFA) derivatives 4-O-acetyl BFA, 7-O-acetyl BFA, and 4-O-D-glucosyl BFA were found by the microbial conversion of BFA. 4-O-D-Glucosyl BFA is a novel compound produced by the conversion of BFA with Streptomyces sp. Q53834. The cytotoxicity and antifungal activity of all of the compounds were markedly less than those of BFA.

Protein Modifications in the RER
Broadly, these modifications can be categorized into four main categories โ glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal sequences.
