Methods Blood samples were obtained from 5 patients with AIDS, the C2~C3 region of HIV-1 envelope gene was amplified by nested polymerse chain reaction from plasma of each patient, and then subject to sequencing, clonal-quasispecies analysis, and the accumulation of synonymous and nonsynonymous substitutions as well as ds/dn ratios were calculated.

采用套式聚合酶链反应方法对5例艾滋病患者血浆HIV-1 env基因C2~V3区进行PCR扩增，产物经纯化后克隆至pMD-18T载体中，每例患者分别挑取5~8个克隆，共34株，完成阳性克隆的鉴定、抽提纯化和测序，将获得的DNA序列及核苷酸序列进行分析，并计算其核苷酸同源替换率与非同源替换率的比值。

These results indicated that the genetic variation within exon 2 appeared to have largely arisen by gene recombination and balancing selection. Alignment of the deduced amino acid sequences of the β1 domain coded by exon 2 revealed 6 synonymous mutations and 27 nonsynonymous substitutions at the 33 disparate sites.

对B-LBⅡ等位基因第二外显子所编码的B-LBⅡ分子β1结构域氨基酸序列比对发现，31个B-LBⅡ新等位基因属于26个等位基因主型；在β1结构域氨基酸序列的33个变异位点上，存在6个同义替换和27个错义替换。

Second, residues in the reactive site of the inhibitor were replaced by the consensus substrate recognition sequence of furin, namely, Arg at P_1, Lys at P_2, Arg at P_4 and Arg at P_6. In addition, the P_7 residue Asp was substituted with Ala to avoid possible electrostatic interference with furin inhibition. Finally, the extra N and C terminal residues beyond the doubly conjugated disulfide loops were further truncated. However, all resultant synthetic peptides were found to be temporary inhibitors of furin and kexin during a prolonged incubation, with the scissile peptide bond between P1 and P'1 cleaved to different extents by the enzymes.

高活性、低分子量的furin酶抑制剂有可能发展成为新型的抗细菌内毒素和抗病毒感染的药物，我们以绿豆胰蛋白酶抑制剂Lys片段长链22肽为模板，设计了一系列能抑制furin和kexin活性的突变体，采用如下三种方法逐步优化：一、去除Lys片段长链三对二硫键中的一对，用Ser替换Cys，减少可能存在的二硫键错误配对；二、抑制剂的活性中心根据furin底物的专一性逐步改变，即P1、P2、P4和P6位分别变为Arg、Lys、Arg和Arg，同时为了避免P7 Asp和P6 Arg之间可能存在的相互作用，将P7位Asp替换为Ala；三、将两对二硫键形成的双环的外面5个氨基酸残基去除。
