HHsearch alignment for GI: 254781020 and conserved domain: TIGR01768

>TIGR01768 GGGP-family geranylgeranylglyceryl phosphate synthase family protein; InterPro: IPR008205 This family contains prokaryotic proteins that are related to pcrB. Staphylococcus aureus chromosomal gene pcrA encodes a protein with significant similarity (40 0dentity) to two Escherichia coli helicases: the helicase II encoded by the uvrD gene and the Rep helicase. PcrB gene seems to belong to an operon containing at least one other gene, pcrBA, downstream from pcrB . The PcrB proteins often contain an FMN binding site although the function of these proteins is still unknown..
