An allosteric enzyme that regulates glycolysis by catalyzing the transfer of a phosphate group from ATP to fructose-6-phosphate to yield fructose-1,6-bisphosphate. In humans, PHOSPHOFRUCTOKINASE-1 in muscle exists as the homotetramer of M subunits. Defects in this muscle enzyme cause GLYCOGEN STORAGE DISEASE TYPE VII, also known as Tarui's disease.
The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)
