在逆转录病毒中,慢病毒的表面(SU)和跨膜(TM)糖蛋白仅通过非共价键连接。然而,对于某些 C 型逆转录病毒,一小部分 SU 蛋白已被证明通过二硫键与其 TM 蛋白连接,其余部分则为非共价连接。 HIV-1 SU 糖蛋白羧基末端附近的区域与 TM 糖蛋白的接触有关。计算机模型表明,不同的慢病毒和肿瘤病毒SU糖蛋白的这个区域形成了一个结构保守的“口袋”,它可以容纳由含有CxxxxxC(慢病毒)或CxxxxxxCC(C型和D型病毒)基序的TM蛋白中的免疫显性区域形成的“旋钮”状突起。一种抗独特型单克隆抗体是针对与 HIV-1 gp120“口袋”中的序列反应的单克隆抗体而产生的,被发现与靠近 CxxxxxC 基序的合成肽结合。这表明慢病毒和肿瘤病毒的 SU-TM 连接机制的一部分是“旋钮和插座”结构,并且 SU 和 TM 蛋白之间的相互作用在慢病毒和 C 型以及 D 型病毒的一个区域中是相似的。保守的旋钮和插座连接可能与所有这些逆转录病毒广泛共有的病毒细胞膜融合机制有关。
Among the retroviruses, the surface (SU) and transmembrane (TM) glycoproteins of lentiviruses are linked exclusively by noncovalent bonds. For some C-type retroviruses, however, a small proportion of the SU proteins has been shown to be linked to their TM proteins by a disulfide bond, with the remainder being noncovalently associated. A region near the carboxyl terminus of the HIV-1 SU glycoprotein has been implicated in contacting the TM glycoprotein. Computer modelling indicates that this region of divergent lentivirus and oncovirus SU glycoproteins forms a structurally conserved "pocket" which could accommodate a "knob"-like protrusion formed by an immunodominant region in the TM protein containing the CxxxxxC (lentiviruses) or CxxxxxxCC (C- and D-type viruses) motif. An anti-idiotypic monoclonal antibody, raised against a monoclonal antibody reacting with a sequence in the "pocket" of HIV-1 gp120, was found to bind to synthetic peptides close to the CxxxxxC motif. It is suggested that part of the SU-TM linkage mechanism for the lentiviruses and oncoviruses is a 'knob and socket' structure and that the interaction between SU and TM proteins is similar in one region for lentiviruses and C-type as well as D-type viruses. The conserved knob and socket linkage may be relevant to a mechanism for viral-cell membrane fusion that is broadly common to all of these retroviruses.
