A calmodulin‐specific radioimmunoassay was used to measure the calmodulin present in 5 filamentous fungi and 14 yeasts. The filamentous organisms contained from 2.0 –6.5 μg calmodulin per mg soluble protein, whereas the yeasts contained from 0.02–0.89 μg per mg. The size of this difference suggests that the evolutionary transition to yeasts included loss of the extra calmodulin synthetic capacity necessary for mycelial growth.
