Abstract excerpt
The transsulfuration pathways allow the interconversion of homocysteine and cysteine with the intermediary formation of cystathionine. The various organisms studied up to now incorporate reduced sulfur into a three- or a four-carbon chain and use differently the transsulfuration pathways to synthesize sulfur amino acids. In enteric bacteria, the synthesis of cysteine is the first step of organic sulfur metabolism...
