Abstract

Lactococcal oligopeptide-binding protein A (OppA) binds peptides with widely varied lengths and sequences. We previously hypothesized that a hydrophobic pocket in OppA preferentially binds a hydrophobic peptide side chain and thus determines its binding register. Two crystal structures of OppA with different nonapeptides now indeed show binding in different registers.

摘要

乳球菌寡肽结合蛋白 A(OppA)能够结合具有广泛变化长度和序列的肽。我们先前假设 OppA 中的一个疏水口袋优先结合疏水性肽侧链,从而决定其结合位区。现在,有两个与不同九肽的 OppA 的晶体结构确实显示出在不同的结合位区的结合。
