. glycine, l-alanine,l-proline, l-lysine, l-serine, b-alanine, taurine, sarcosine,dimethylglycine, glycine betaine, trimethylamine N-oxide, and cytidine 2¢-3¢ cyclic monophosphate were also obtainedfrom. alanine, proline, serine, lysine, b-alanine and taurine) that have no significant effects on both DGD° and kcat. (b) Class II represents methylamines (sarco-sine, dimethylglycine, betaine,. equilibrium and, hence, there is no increase in catalytic efficiency in thepresence of this group of osmolytes. Interestingly,there is a linear relationship between DDGD° and Dlog(kcat⁄ Km) in...
