A small Ca2 binding protein that modifies the activity of many enzymes and other proteins in response to changes of Ca2+ concentration is called as
B. Calmodulin
C. Collagen
D. Kinesin
Ans. B.
Calmodulin.
It is a
calcium-dependent regulatory protein. it has four Ca2-binding sites. If all the
sites are fully occupied, Ca2+ sites allow calmodulin to activate the ion
channels and enzymes. Calmodulin is involved in regulation of a number of
kinases and enzymes.
