Range 8.8 fast growing cells: 5.2 slow growing cells aa/sec/ribosome
Organism Budding yeast Saccharomyces cerevisiae
Reference Waldron C, Jund R, Lacroute F. Evidence for a high proportion of inactive ribosomes in slow-growing yeast cells. Biochem J. 1977 Dec 15 168(3):409-15. p.411 table 1PubMed ID343781
Method The times required to synthesize polypeptides of different molecular weights were determined from the kinetics of incorporation of a radioactive amino Acid.
Comments Nitrogen source of fast growing cells (0.54 doublings/hour) was (NH4)2SO4. Nitrogen source of slow growing cells (0.31 doublings/hour) was L-Proline
