Protein Family Models

phosphonate C-P lyase system protein PhnK is a component of the carbon-phosphorus (C-P) lyase system, which is involved in alkylphosphonate uptake and C-P lyase activity; similar to the ATPase subunits of ABC transporters specific for the import of dipeptides, oligopeptides, and nickel

Members of this family are the PhnK protein of C-P lyase systems for utilization of phosphonates. These systems resemble phosphonatase-based systems in having a three component ABC transporter, where TIGR01097 is the permease, TIGR01098 is the phosphonates binding protein, and TIGR02315 is the ATP-binding cassette (ABC) protein. They differ, however, in having, typically, ten or more additional genes, many of which are believed to form a membrane-associated complex. This protein (PhnK) and the adjacent-encoded PhnL resemble transporter ATP-binding proteins but are suggested, based on mutatgenesis studies, to be part of this complex rather than part of a transporter per se.
