pH-dependent changes in structure and RNA-binding activity of casein kinase 2 from Rana temporaria oocytes.

abstract：:Endothelin-1 (ET-1) dose-dependently increased HIF1α expression in pulmonary artery smooth muscle cells (PASMCs). Inhibition of protein synthesis did not affect ET-1-induced HIF1α expression. The maximum effect of ET-1 was similar to that caused by proteasome inhibitor MG132. Further study indicates that ET-1 also dos...

abstract：:Brain nitric oxide synthase is a Ca2+/calmodulin-regulated enzyme which converts L-arginine into NO. Enzymatic activity of this enzyme essentially depends on NADPH and is stimulated by tetrahydrobiopterin (H4biopterin). We found that purified NO synthase contains enzyme-bound H4biopterin, explaining the enzymatic acti...
