Substrate specificity of MTBSLS constructs. a Various MTBSLS constructs that were evaluated. b Comparison of the preference of different MTBSLS constructs to L-Phe-SNAC and L-Leu-SNAC. The ratio of methylated products formed from 5 mM L-Phe-SNAC or 5 mM L-Leu-SNAC over a 10-min reaction time are plotted. The data for cMT and XLcMT represent two separate preparations of crosslinked protein, assayed in duplicate
