Comments |
"In quantitative terms, where does RNase E invest its enzymatic turnovers? This can be estimated with the following assumptions. In a culture of Escherichia coli K12 that grows with a doubling time of about 30 minutes, there will be approximately 50,000 ribosomes [primary source], 375,000 tRNAs [BNID 108611] (7.5 per ribosome) and perhaps a single to at most ten copies of each of the ~2,000 mRNAs per cell." |
