This entry represents a small domain of approximately 100 residues, classified as UPF0166, found predominantly in Bacteria (Actinomycetota and Pseudomonadota) and also in Archaea. The domain adopts a PII-like fold and is a member of the GlnB-like superfamily (CL0089). The crystal structure of TM0021 (Swiss:Q9WXM9) from Thermotoga maritima has been determined at 2.5 Angstrom resolution [1]. In Pelobacter carbinolicus, a member of this family (Pcar_0334) has been described as a possible modulator of transport, distantly related to the GlnK protein that controls the ammonium transport channel. Some proteins contain tandem repeats of this domain. The domain is predicted to form a homotrimer. The function of this domain remains to be determined.
