pfam10442: FIST_C (This model is not part of the current CDD release)
FIST C domain
The FIST C domain is a novel sensory domain, which is present in signal transduction proteins from Bacteria, Archaea and Eukarya. Chromosomal proximity of FIST-encoding genes to those coding for proteins involved in amino acid metabolism and transport suggest that FIST domains bind small ligands, such as amino acids.
