This is a sensor domain found in solute-binding protein family 3 members from Gram-positive bacteria, Gram-negative bacteria and archaea. It can also be found in the N-terminal of the membrane-bound lytic murein transglycosylase F (MltF) protein. This domain recognises Nicotinate, quidalnate, pyridine-2,5-dicarboxylate and salicylate [1].	Domain
