Radical-mediated ring contraction in the biosynthesis of 7-deazapurines.

abstract：:When a protein's function cannot be experimentally determined, it can often be inferred from sequence similarity. Should this process fail, analysis of the protein structure can provide functional clues or confirm tentative functional assignments inferred from the sequence. Many structure-based approaches exist (e.g. ...
