Abstract

Codon context is an important feature of gene primary structure that modulates mRNA decoding accuracy. We have developed an analytical software package and a graphical interface for comparative codon context analysis of all the open reading frames in a genome (the ORFeome). Using the complete ORFeome sequences of Saccharomyces cerevisiae, Schizosaccharomyces pombe, Candida albicans and Escherichia coli, we show that this methodology permits large-scale codon context comparisons and provides new insight on the rules that govern the evolution of codon-pair context.

摘要

密码子上下文是基因一级结构的一个重要特征,它能调节mRNA解码的准确性。我们开发了一个分析软件包和一个图形界面,用于对基因组中的所有开放阅读框(ORFeome)进行密码子上下文比较分析。利用酿酒酵母、粟酒裂殖酵母、白色念珠菌和大肠杆菌的完整ORFeome序列,我们表明这种方法允许进行大规模的密码子上下文比较,并为支配密码子对上下文进化的规则提供了新的见解。
