This domain is found at the N-terminal end of CDP-alcohol phosphatidyltransferase family protein from Archaeoglobus fulgidus (AF_2299) and similar archaeal proteins. AF_2299 is a member of a family of membrane-embedded enzymes known as CDP-alcohol phosphotransferases (CDP-APs) involved in the formation of polar phospholipids. This integral membrane phosphotransferase is organised into two distinct domains. This entry represents the N-terminal cytoplasmic domain, which has structural similarity to the cytidyltransferases [1-3].	Domain
