    • Human cytomegalovirus (HCMV) protease is a slow-processing enzyme in vitro. Disclosed herein are improved fluorogenic and radiometric peptide substrates for CMV protease. The improved substrates have a Tbg-Tbg-Asn(NMe2) sequence replacing the Val-Val-Asn sequence, corresponding to the P4-P2 residues of the maturation site of the enzyme. The incorporation of this new sequence in a variety of substrates has afforded substrates with improved kinetic parameters compared to homologues containing the natural sequence only. For example, the substrate 2-aminobenzoyl-Tbg-Tbg-Asn(NMe2)-Ala &darr& Ser-Ser-Arg-Leu-Tyr(3-NO2)ARG-OH displayed a kcat/Km value of 15940 M s , i.e. over 60-fold greater than that of the equivalent, non-optimized substrate in identical conditions. The new substrates find use in assays which can evaluate and characterize HCMV protease inhibitors having low nanomolar potency.
    • 人巨细胞病毒(HCMV)蛋白酶是体外缓慢加工的酶。 本文公开了用于CMV蛋白酶的改进的荧光和辐射肽底物。 改进的底物具有代替Val-Val-Asn序列的Tbg-Tbg-Asn(NMe2)序列,对应于酶的成熟位点的P4-P2残基。 与仅含有天然序列的同源物相比,将这种新序列并入多种底物中提供了具有改善的动力学参数的底物。 例如,底物2-氨基苯甲酰基-Tgg-Tbg-Asn(NMe2)-Ala&amp; darr&Ser-Ser-Arg-Leu-Tyr(3-NO2)ARG-OH显示出kCl / Km值为15940M -1 s -1,即相同条件下的等效非优化底物的60倍以上。 新的底物可用于可以评估和表征具有低纳摩尔效力的HCMV蛋白酶抑制剂的测定中。
