An efficient chemoselective method for the creation of semisynthetic lipases by site-specific incorporation of tailor-made peptides on the lipase-lid site was developed. These new enzymes showed excellent improved specificity and regio- or enantioselectivity in different biotransformations.
CHEMICALLY MODIFIED NUCLEOSIDE 5'-TRIPHOSPHATES FOR THERMALLY INITIATED AMPLIFICATION OF NUCLEIC ACID

Page/Page column 59-60, (2010/01/07)
Provided herein are methods and compositions for nucleic acid amplification. These methods involve the use of 3'-substituted nucleoside 5'-triphosphates or 3'-substituted terminated primers in nucleic acid amplification reactions. In certain aspects, the methods are accomplished by use of 3'-substituted NTPs and/or 3'-substituted terminated primers which provide utility in nucleic acid amplification. In preferred embodiments, the NTPs and/or primers are substituted at the 3'-position with particular heat labile chemical groups such as ethers, esters or carbonate esters.

A set of nucleotide analogues containing a stable trigonal bipyramidal phosphorus (PV TBP) moiety (5-11) has been developed, and their conformational properties were studied with 300- and 500-MHz 1H NMR.In the solvent acetone-d6, it is found that the conformation of the model compounds is determined by a hydrogen bond between the backbone atom O5', and the base proton H6 (pyrimidine base) or H8 (purine base), resulting in a preference for the standard gauche(+) conformation around the C4'-C5' bond.In the hydrogen bond disrupting solvent DMSO-d6, the PV TBP nucleotides 5-8 clearly show conformational transmission, i.e., a preference for the unusual gauche(-) (g-) rotamer around the C4'-C5' bond is found.This structural distortion opposes stacking of the bases, as is confirmed by the observation that the preference for g- is strongest for 7 and 8, in which stacking is eliminated.The present results provide support to our earlier proposition that formation of PV TBP locations in DNA can lead to a marked change of the secondary structure (Buck, H.M.Recl.Trav.Chim.Pays-Bas 1980, 99, 181).
