Abstract

SUMMARY: Twelve mutants blocked in chloramphenicol biosynthesis were isolated. Two of these (Cml-1 and Cml-12) were apparently blocked in the conversion of chorismic acid to -aminophenylalanine and three (Cml-4, Cml-5 and Cml-8) accumulated -aminophenyl-alanine and may have been blocked in the hydroxylation reaction that converted this intermediate to -aminophenylserine. One mutant (Cml-2) accumulated --1--nitro-phenyl-2-propionamido-1,3-propanediol and --1--nitrophenyl-2-isobutyramido-1,3-propanediol, indicating that chlorination of the x--acyl group of chloramphenicol was blocked. The remaining six strains did not excrete any detectable chloramphenicol pathway intermediates.
