    摘要: The presently disclosed subject matter demonstrates that ThnG and ThnQ enzymes encoded by the thienamycin gene cluster in Streptomyces cattleya oxidize the C-2 and C-6 moieties of carbapenems, respectively. ThnQ stereospecifically hydroxylates PS-5 giving N-acetyl thienamycin. ThnG catalyzes sequential desaturation and sulfoxidation of PS-5, giving PS-7 and its sulfoxide. The ThnG and ThnQ enzymes are relatively substrate selective, but give rise to the oxidative diversity of carbapenems produced by S. cattleya, and orthologues likely function similarly in allied streptomyces.

    摘要: This invention relates to the new antibiotic, desacetyl 890A.sub.10, active against both gram-positive and gram-negative bacteria, which is produced by treating 890A.sub.10 with an N-acetyl-890A.sub.10 amidohydrolase produced by a soil microorganism isolated by enrichment techniques. This invention also relates to the process by which 890A.sub.10 is enzymatically deacetylated.
