HHsearch alignment for GI: 254781020 and conserved domain: cd02812

>cd02812 PcrB_like PcrB_like proteins. One member of this family, a protein from Archaeoglobus fulgidus, has been characterized as a (S)-3-O-geranylgeranylglyceryl phosphate synthase (AfGGGPS). AfGGGPS catalyzes the formation of an ether linkage between sn-glycerol-1-phosphate (G1P) and geranylgeranyl diphosphate (GGPP), the committed step in archaeal lipid biosynthesis. Therefore, it has been proposed that PcrB-like proteins are either prenyltransferases or are involved in lipoteichoic acid biosynthesis although the exact function is still unknown.
