Synthesized substrate PNP (NAcGlc) 3 [p Nitrophenyl β D N',N'',N''' Triacetyl chitotriose] was used to measure the lysozyme activity of the mutant. The result showed that the mutant acquired 5.26% lysozyme activity of recombinant HEWL.
合成底物 p Nitrophenyl β D N’ ,N’’ ,N’’’ Triacetyl chitotriose [pNP (NAcGlc) 3]与突变体蛋白的反应时间曲线证明突变体蛋白获得了部分溶菌酶生物活性 ,为重组鸡蛋清溶菌酶 (HEWL)的 5 .2 6 % .
In the second part, atom transfer radical copolymerization of styrene and bismaleimide was carried out using CuBr/bpy or CuBr/PMDETA complex as catalyst and 2-bromo-2-methyl-propionic acid ethyl ester as initiator, and star polystyrenes were obtained.
在第二部分中,以溴异丁酸乙酯为引发剂,CuBr/2,2’-联吡啶(bpy)为催化剂或CuBr/N, N, N’, N”, N’’-五甲基二乙撑三胺(PMDETA)为催化剂,进行苯乙烯和双马来酰亚胺的原子转移自由基共聚合,得到了星形聚苯乙烯。
The method applies to the standard arithmetic subgroups ofSO(n,1) (a case which was proved previously by Millson [Mi]), to the non-arithmetic lattices inSO(n,1) constructed by Gromov and Piatetski-Shapiro [GPS] and to groups generated by reflections.
We express them in terms of generatorsEij ofU(gl(n)) and as differential operators on the space of matrices These expressions are a direct generalization of the classical Capelli identities.
In this paper, we prove the degenerations of Schubert varieties in a minusculeG/P, as well as the class of Kempf varieties in the flag varietySL(n)/B, to (normal) toric varieties.
