Compositional variation in bacterial genes and proteins with potential expression level
چکیده انگلیسی

Usage of guanine and cytosine at three codon sites in eubacterial genes vary distinctly with potential expressivity, as predicted by Codon Adaptation Index (CAI). In bacteria with moderate/high GC-content, G3 follows a biphasic relationship, while C3 increases with CAI. In AT-rich bacteria, correlation of CAI is negative with G3, but non-specific with C3. Correlations of CAI with residues encoded by G-starting codons are positive, while with those by C-starting codons are usually negative/random. Average Size/Complexity Score and aromaticity of gene-products decrease with CAI, confirming general validity of cost-minimization principle in free-living eubacteria. Alcoholicity of bacterial gene-products usually decreases with expressivity.
