RESUMO
Two-dimensional analysis of tryptic peptides from [35S]methionine-labeled methyl-accepting chemotaxis proteins, MCP I and MCP II, demonstrates a high degree of homology between the two proteins. After the methylation sites were labeled with S-adenosyl-L-methyl-3H]methionine, peptides of three distinct migrations in each protein were found to carry a methyl group. These multiple methylations appear to be responsible in part for the observed multiple banding patterns on sodium dodecyl sulfate/polyacrylamide slab gels.
