This domain is a GAF-like domain found at the N-terminus of several bacterial GTP-sensing transcriptional pleiotropic repressor CodY proteins. This domain is involved in GTP binding and also branched chain amino acids (Matilla et. al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043). CodY has been found to repress the dipeptide transport operon (dpp) of Bacillus subtilis in nutrient-rich conditions [1]. The CodY protein also has a repressor effect on many genes in Lactococcus lactis during growth in milk [2].	Domain
