Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motility and fusion. They share a fold in common with all Ras GTPases: this is a six-stranded beta-sheet surrounded by five alpha-helices [1].

This may be a family of flavocytochromes capable of moving electrons across the plasma membrane [1]. The Frp1 protein Swiss:Q04800 from S. pombe is a ferric reductase component and is required for cell surface ferric reductase activity, mutants in frp1 are deficient in ferric iron uptake [1]. Cytochrome B-245 heavy chain Swiss:P04839 is a FAD-dependent dehydrogenase it is also has electron transferase activity which reduces molecular oxygen to superoxide anion, a precursor in the production of microbicidal oxidants [2]. Mutations in the sequence of cytochrome B-245 heavy chain (gp91-phox) lead to the X-linked chronic granulomatous disease. The bacteriocidal ability of phagocytic cells is reduced and is characterised by the absence of a functional plasma membrane associated NADPH oxidase [3]. The chronic granulomatous disease gene codes for the beta chain of cytochrome B-245 and cytochrome B-245 is missing from patients with the disease [4].
