<p>This entry represents a family with an N-terminal region similar to proteobacterial glutamate-cysteine ligase (gamma-glutamylcysteine synthetase). The C-terminal region is homologous to cyanophycin synthetase of cyanobacteria, and (shown by PSI-BLAST) to D-alanine-D-alanine ligases. Cyanophycin is a storage molecule composed of arginine, aspartic acid, and some glutamic acid. Members of this family are found in Listeria and Enterococcus, Gram-positive lineages in which glutathione is produced [<cite idref="PUB00007957"/>], and in proteobacterium <taxon tax_id="747">Pasteurella multocida</taxon>.</p> Glutamate--cysteine ligase-related
