Structural studies of the S-adenosyl-L-methionine binding proteins

The post-genomic era produces an overwhelming amount of experimental data, but majority of such data lacks the characterization of its functions. Structure based approaches are useful to understand and characterize the functional aspects of proteins. Given the burgeoning requirement of understanding the functional aspects of various enzymes, we report a systematic structure based study of methyltransferases bound with S-adenosyl-L-methionine (SAM). Through this work, we identified the conserved amino acids of methyltransferase, which are interacting with SAM.
