Identification
Name:D-Methionine
DescriptionD-methionine is a member of the chemical class known as Alpha Amino Acids and Derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon).Although L-methionine is a potent inhibitor of D-methionine uptake, D-methionine has little or no effect on the uptake of the L-isomer. (PMID 318639) A transporter of Escherichia coli specific for L- and D-methionine is the prototype for a new family within the ABC superfamily. (PMID 12819857) The metD D-methionine transporter locus of Escherichia coli is an ABC transporter gene cluster. (PMID 12169620)
