Curated sequence SYNPCC7942_2156-MONOMER: glutamine synthetase, type I
Comment: A protein from Cupriavidus necator is reported to be a 3-hydroxylaminophenol mutase (see Swiss-Prot 3HAPM_CUPNJ), involved in 3-nitrophenol degradation. That is the only glutamine synthetase-like protein in the proteome of Cupriavidus necator (strain JMP 134 / LMG 1197) [see proteome UP000002697] and is 96% identical to the essential protein RR42_RS12995 from Cupriavidus basilensis 4G11. It is probably a glutamine synthetase. SYNPCC7942_2156-MONOMER is annotated with the same reaction, but was not originally given this EC number.
