A relationship between L-serine degradation and methionine biosynthesis in Escherichia coli K12.

Journal of general microbiology - 1 Jun 1990

Brown E A, D'Ari R, Newman E B

Abstract excerpt

While wild-type Escherichia coli K12 cannot grow with L-serine as carbon source, two types of mutants with altered methionine metabolism can. The first type, metJ mutants, in which the methionine biosynthetic enzymes are expressed constitutively, are able to grow with L-serine as carbon source. Furthermore, a plasmid carrying the metC gene confers ability to grow on L-serine. These observations suggest that in...
