Abstract

The 49630 bp spo0H-rrnH region of the Bacillus subtilis genome has been fully sequenced. The sequence contains one partial and 62 complete ORFs, one partial and three complete rRNA genes and a cluster of six tRNA genes. The direction of the transcription and translation of 61 ORFs is the same as that of the movement of the replication fork. A homology search of 40 ORFs in newly determined sequence revealed that 27 of them had significant similarity to known proteins such as elongation factor G, elongation factor Tu, pseudouridine synthase I and ribsosomal proteins. Two adjacent genes, ybaD and ybaE, appeared to encode proteins belonging to the ATP-binding cassette (ABC) family.

摘要

枯草芽孢杆菌基因组中49630 bp的spo0H-rrnH区域已完成全序列测定。该序列包含1个部分开放阅读框(ORF)和62个完整的ORF、1个部分核糖体RNA(rRNA)基因和3个完整的rRNA基因以及一簇6个转运RNA(tRNA)基因。61个ORF的转录和翻译方向与复制叉移动方向相同。对新测定序列中的40个ORF进行同源性搜索发现,其中27个与已知蛋白质具有显著相似性,如延伸因子G、延伸因子Tu、假尿苷合酶I和核糖体蛋白。两个相邻基因ybaD和ybaE似乎编码属于ATP结合盒(ABC)家族的蛋白质。
