Ref reports using the concentrations of 25 soluble proteins reported by primary source, p. 178 and 180 table AII-http://kirschner.med.harvard.edu/files/bionumbers/MW%20and%20number%20of%20subunits%20of%20cytosolic%20enzymes.pdf |
| Comments |
We counted the number of subunits of 23 enzymes reported by primary source in p. 178 and 180 (omitting 3 enzymes with double data and the citric acid cycle enzymes on p. 180). 3 monomers, 7 dimers, 9 tetramers, 2 hexamers, 1 decamer and 1 dodecamer (12-mer) were counted giving a median of 4 and an average of about 3.8.
