This entry represents the C-terminal domain found in the YegS protein [1,2]. It is related to the beta sandwich domain of NAD kinases. The structure of YegS reveals a two-domain protein with the active site crevice found between the two domains. The C-terminal domain contains 13 beta-strands and two alpha-helices. The likely substrate for YegS is phosphatidylglycerol [1].
