By interaction with sarcoplasmic reticulum from rabbit muscle G-actin loses the capability to polymerize. The modification of actin is due to the concomitant action of the Ca2+ ATPase and of an ADPase embedded in the sarcoplasmic reticulum vesicles. Methyl isobutyl xanthine increases the rate of modification of actin by the sarcoplasmic reticulum vesicles by increasing the rate of the exchange of the actin-bound nucleotide.

Abstract
By interaction with sarcoplasmic reticulum from rabbit muscle G-actin loses the capability to polymerize. The modification of actin is due to the concomitant action of the Ca2+ ATPase and of an ADPase embedded in the sarcoplasmic reticulum vesicles. Methyl isobutyl xanthine increases the rate of modification of actin by the sarcoplasmic reticulum vesicles by increasing the rate of the exchange of the actin-bound nucleotide.File in questo prodotto:
