Cytochrome b558 is a crucial component of the Phagocyte NADPH Oxidase (NOX2) complex, which plays a significant role in the immune system by generating reactive oxygen species (ROS) to eliminate pathogens. This protein is composed of two subunits, a heavy chain (α) and a light chain (β), and is involved in the electron transport chain, transferring electrons from NADPH to molecular oxygen, thereby producing superoxide anions. Cytochrome b558 is essential for the proper functioning of neutrophils and other phagocytic cells, as it helps in the destruction of invading microorganisms and maintaining cellular homeostasis. Its dysfunction has been implicated in various diseases, including chronic granulomatous disease, which is characterized by recurrent infections due to the impaired production of ROS.
The CAS Registry Mumber 9064-78-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,6 and 4 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 9064-78: (6*9)+(5*0)+(4*6)+(3*4)+(2*7)+(1*8)=112 112 % 10 = 2 So 9064-78-2 is a valid CAS Registry Number.
