用随机组合多肽文库方法[Wu,J.,Ma,Q.N.&Lam,K.S.(1994)BioChemical 33,14825-14833]鉴定了一种新的多肽YIYGSFK,它是p60c-src蛋白酪氨酸激酶的底物。质谱分析表明,该末端的酪氨酸-3为磷酸化位点。动力学研究表明,p60c-src的Km值为55μM,比p34cdc2[cdc2(6-20),KVEKIGEGTYGVYK]衍生的多肽低6.4倍,p34cdc2被认为是src家族蛋白酪氨酸激酶的特异和有效底物。比较YIYGSFK和cdc2(6-20)作为各种Src家族和非Src家族蛋白酪氨酸激酶底物的特异性,表明YIYGSFK是更特异和更有效的Src家族蛋白酪氨酸激酶底物。©孟克斯加德1995年。
Using a random combinatorial peptide library method [Wu, J., Ma, Q. N. & Lam, K. S. (1994)Biochemistry33, 14825–14833] a novel peptide, YIYGSFK, was identified as a substrate for p60c‐srcprotein tyrosine kinase. Mass spectrometric analysis showed that tyrosine‐3 from theN‐terminus was the phosphorylation site. Kinetic studies showed that theKmof YIYGSFK for p60c‐srcwas 55 μM, about 6.4‐fold lower than a peptide derived from p34cdc2[cdc2(6–20), KVEKIGEGTYGVVYK], which had been reported to be a specific and efficient substrate for the Src‐family protein tyrosine kinases. Comparison of the specificity of YIYGSFK and cdc2(6–20) as a substrate for various Src‐family and non‐Src‐family protein tyrosine kinases suggests that YIYGSFK is a much more specific and efficient substrate for the Src‐family protein tyrosine kinases. © Munksgaard 1995.
