Microsomal phosphate transport protein

Microsomal phosphate transport protein (T2Q ) which mediates the efflux of P , an inhibitor of the glucose-6-phosphatase, from the lumen of the endoplasmic reticulum to the cytosol ... 

Microsomal phosphate/pyrophosphate transport protein M.W. 37,000), which transports phosphate, pyrophosphate, and carbamoyl phosphate, which are substrates for glucose-6-phosphatase and... 

Proteins are hydrolyzed to amino acids, which enter the Krebs cycle after transportation in the blood and transamination in the liver. The reversal of the Krebs cycle and the Embden-Meyerhof pathway converts the Krebs cycle substrates into glucose. The conversion of glucose-6-phosphate to glucose is catalyzed by a microsomal enzyme, glucose-6-phosphatase. The mechanisms controlling gluconeogenesis are discussed in more detail in Chapter 16.
