Abstract

The BolA-like proteins are widely conserved from prokaryotes to eukaryotes. The BolA-like proteins seem to be involved in cell proliferation or cell-cycle regulation, but the molecular function is still unknown. Here we determined the structure of a mouse BolA-like protein. The overall topology is alphabetabetaalphaalphabetaalpha, in which beta(1) and beta(2) are antiparallel, and beta(3) is parallel to beta(2). This fold is similar to the class II KH fold, except for the absence of the GXXG loop, which is well conserved in the KH fold. The conserved residues in the BolA-like proteins are assembled on the one side of the protein.

摘要

BolA样蛋白从原核生物到真核生物广泛保守。BolA样蛋白似乎参与细胞增殖或细胞周期调控,但其分子功能仍不清楚。在此我们确定了一种小鼠BolA样蛋白的结构。其整体拓扑结构为alphabetabetaalphaalphabetaalpha,其中β(1)和β(2)是反平行的,β(3)与β(2)平行。这种折叠与II类KH折叠相似,只是缺少在KH折叠中保守性良好的GXXG环。BolA样蛋白中的保守残基聚集在蛋白质的一侧。
