| 20090192720 | METHODS AND COMPOSITIONS FOR DETERMINING ENZYMATIC ACTIVITY AND SPECIFICITY OF METHYLTRANSFERASES - The invention provides crystalline O-methyltransferases and isolated non-native O-methyltransferases as well as sets of their structural coordinates. Also provided are methods of predicting the activity or substrate specificity of putative O-methyl-transferases, methods of identifying potential substrates of O-methyltransferases, and methods of identifying potential inhibitors of methyltransferases. | 07-30-2009 |
