Comments	“[Researchers] display estimates of the predicted transcription factors in five genomes in Table 1, ranging from about 300 in E. coli to over 3000 in humans. These constitute between 6% (in E. coli and yeast) and 8% (in human) of the encoded proteins in these organisms. van Nimwegen’s [ref 24 PMID 12957540] earlier observation that larger genomes tend to have more transcription factors per gene is in accordance with the trend seen in eukaryotes (Table 1).” See notes beneath table
