Choline kinase catalyses the committed step in the synthesis of phosphatidylcholine by the CDP-choline pathway [1]. This alignment covers the protein kinase portion of the protein. The divergence of this family makes it very difficult to create a model that specifically predicts choline/ethanolamine kinases only.	Domain
