We have cloned and sequenced a gene coding for a putative shape-determining protein (MreB) highly homologous to the mreB gene product of Escherichia coli. The amino acid (aa) identity was 53% and the similarity 72%. The gene is expressed early in the logarithmic phase. The aa sequence comparison showed that the protein, like the E. coli MreB, has structural similarity to actin and heat-shock protein Hsc70 encoded by a new super-gene family.
我们已经克隆并测序了一个编码假定形状决定蛋白（MreB）的基因，该蛋白与大肠杆菌的mreB基因产物高度同源。氨基酸（aa）同一性为53%，相似性为72%。该基因在对数生长期早期表达。氨基酸序列比较表明，该蛋白与大肠杆菌的MreB一样，与由一个新的超基因家族编码的肌动蛋白和热休克蛋白Hsc70具有结构相似性。
