. "The final step in the pathway involves the addition of L-serine, with concomitant removal of CMP, leading to the production of unsaturated archaetidylserine." . "Responsible for the formation of archaea-specific sn-glycerol-1-phosphate, the first step in the biosynthesis of polar lipids in archaea." . "It is the enantiomer of sn-glycerol 3-phosphate, the form of glycerophosphate found in bacteria and eukaryotes." . "The other enzymes involved in the biosynthesis of polar lipids in archaea are EC 2.5.1.41 and EC 2.5.1.42, which together alkylate the hydroxy groups of glycerol 1-phosphate to give unsaturated archaetidic acid, which is acted upon by EC 2.7.7.67 to form CDP-unsaturated archaeol." . "Activity of the enzyme is stimulated by K(+)." . . . "sn-glycerol-1-phosphate dehydrogenase" . "Glycerol-1-phosphate dehydrogenase (NAD(P)(+))" . "Gro1PDH" .
