Method "Protein length information was retrieved from E. coli K12 genome which was downloaded from Genbank. All the proteins were first mapped to their PIDs for length information retrieval."
Comments "...[researchers] performed analyses to investigate the relationship between protein length and gene importance in E. coli K12. As shown in Table 1, the average lengths of protein products were 343.2 and 329.9 [table shows 329.0] for essential and nonessential genes, respectively. The difference between these values proves not to be statistically significant (Mann–Whitney test, P = 0.697), suggesting that essential gene protein products do not differ in average length from nonessential gene products."
