further facilitate the rational engineering of this enzyme to become a specific 4-arginine hydroxylase. We subsequently demonstrate the utility of this engineered enzyme in the synthesis of a dipeptide fragment of the antibiotic enduracidin. This work highlights the value of applying a bioinformatics-guided approach in the discovery of novel enzymes and engineering of new catalytic activity into existing

N-Tritylated l- and d-methionine and l-glutamic acid were used to obtain novel chiral iso-dideoxynucleoside analogues incorporating a tetrahydrofuranyl or a tetrahyropyranyl ring as the pseudosugar part, and at positions 2 and 3 of the ring an hydroxyethyl group and thymine or adenine, respectively.
