Bp. Valentine et al., EVIDENCE THAT ARGININE IS A LATER METABOLIC INTERMEDIATE THAN ORNITHINE IN THE BIOSYNTHESIS OF CLAVULANIC ACID BY STREPTOMYCES-CLAVULIGERUS, Journal of the Chemical Society, Chemical Communications, (15), 1993, pp. 1210-1211
The feeding of radiolabelled ornithine and arginine to mutants of Stre
ptomyces clavuliyerus auxotrophic for arginine has shown that ornithin
e has to be converted to arginine prior to incorporation into clavulan
ic acid.
