Accordingly, the double deletion mutant VZ6, in which ... not shown). This effect of temperature on cytochrome b content was not observed in the case of the other single deletion mutants. Among the single deletion strains tested...

... in the KHD. Thus, the function of this domain, and the dual regulation by ATP and phosphorylation, are not fully understood. Based on these observations, the current model for NPR-A activation ... of expression. Under such extreme conditions, a substantial fraction of sub- strate would be converted to cGMP and thus the linearity of the enzymatic conditions would be lost...

... containing mutations of the second or third miR-23a binding regions. (C) Similarly, overexpression of miR-23a failed to suppress the EGFP intensity in the reporter vector containing mutation of ... colony forma- tion assays confirmed the active role of miR-23a in the growth promotion of malignant cells. The fundamental function of miRNAs is to regulate their targets by...

The pH dependence of the Pi inhibition of cofilin binding may contribute to the pH regulation of the actin depolymerizing activity of cofilin, which is important in view of the localized ... negli- gible effect on the critical concentration for polymeriza- tion of F-actin in the presence of ATP, because of the protective ATP or ADP–Pi cap at the b...
