9.B.125 The AmpE/CobD (AmpE/CobD) Family Members of the large and diverse AmpE/CobD family have 6 putative TMSs, usually with 280-330aas. They may be involved in signal transduction or cobalamin biosynthesis.
Examples:
TC#	Name	Organismal Type	Example
9.B.125.1.1	AmpE (284aas; 6 putative TMSs). Putative signal transduction protein for ampicillin resistance.	Bacteria	*AmpE of E. coli* (P0AE14)**

9.B.125.1.2	CobD/CbiB cobalamin biosynthesis protein (326aas; 5-6 TMSs)	Bacteria	*CobD of Ralstonia metallidurans* (Q1LK71)**
