The substraterecognition of Pseudomonas cepacia lipase in the acylation of nucleosides was investigated by means of rational substrate engineering for the first time. P. cepacia lipase displayed excellent 3′-regioselectivities (96 to >99%) in the lauroylation of 2′-deoxynucleosides 1a–1e, while low to good 3′-regioselectivities (59–89%) in the lauroylation of ribonucleosides 1f–1j. It might be due
