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.
