electrophoretic analysis of sulfur-labeled proteins and methyl-labeled proteins from trg mutants , which lost the ability of chemotaxis only towards ribose , galactose and their analogs , showed that the product of trg gene was another methyl-accepting protein i.e . a methyl-accepting chemotaxis protein for ribose and galactose ( trg-mcp ) .
