Condenses choline with CDP-diglyceride to produce phosphatidylcholine and CMP. Affects motility, biofilm formation and virulence of this bacterium when there is a complete loss of phosphatidylcholine formation due to absence of both the synthase (pcs) and the methylation (pmtA) pathways. a CDP-1,2-diacyl-sn-glycerol + choline = a 1,2-diacyl-sn-glycero-3-phosphocholine + CMP + H(+) Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
