Biosynthesis pathway of penicillin
WebAbstract. Penicillins and cephalosporins are produced by a wide variety of microorganisms, including some filamentous fungi, many gram-positive streptomycetes, and a few gram-negative unicellular bacteria. All produce these beta-lactam antibiotics by essentially the same biosynthetic pathway. Recently, most of the penicillin and cephalosporin ... WebMar 1, 1997 · l-α-Aminoadipic acid is an intermediate of the l-lysine biosynthetic pathway (reviewed in [1, 5]) and is also provided by catabolic conversion of l-lysine [6, 7]. However, the importance of the catabolic degradation of lysine for penicillin biosynthesis has not been clarified yet.
