A	PF01018	GTP1/OBG (GTP1_OBG)	GTP1/OBG	The N-terminal domain of Swiss:P20964 has the OBG fold, which is formed by three glycine-rich regions inserted into a small 8-stranded beta-sandwich these regions form six left-handed collagen-like helices packed and H-bonded together.	Domain
A	PF09269	Domain of unknown function (DUF1967) (DUF1967)	Domain of unknown function (DUF1967)	Members of this family contain a four-stranded beta sheet and three alpha helices flanked by an additional beta strand. They are predominantly found in the bacterial GTP-binding protein Obg, and are still functionally uncharacterised [1].	Domain
