Abstract
By performing in vivo methylation experiments and using highly resolving NaDodSO4-polyacrylamide gels, we have examined the effects of amino acid attractants on the methylation profile of Bacillus subtilis MCPs. Both increases and decreases have been found to occur in the level of methylation of these proteins. By using competition experiments and Conway diffusion cells, we have found that the demethylation event is correlated with the adaptation process. Gas chromatographic analysis indicates that methanol is evolved upon demethylation of these proteins. As more attractant receptors are titrated, corresponding increases in methanol evolution result. During this period of increased rate of methanol production, bacteria swim smoothly.
