Salmonella typhimurum

On prolonged incubation trimethylpyrrocorphine (136) is formed by over methylation 12a,d). The product of the methylation does not act as an intermediate in the biosynthesis of vitamin B12. The so-called compound-4 (137) is also an over methylated product formed in the vitamin B12 biosynthesis, which is formed with an over expressed methyltransferase (cbi F) from Salmonella typhimurum 87). Compound-4 (137) is closely related to factor S3 (140) (SS). [Pg.35]
