Measuring In Vitro ATPase Activity for Enzymatic Characterization
Published on: August 23, 2016
Abstract:
An assay method for ATP-sulfurylase is described, based on the incorporation of 35SO4(2-) into adenosine-5'-phosphosulfate (and 3-phosphoadenosine-5'-phosphosulfate) and the separation of these compounds by HPLC. Since the enzyme is easily inactivated at temperatures above 20 degrees C during the assay, the reaction time should not exceed 10 min.

ATP Synthase: Mechanism
In animals, the mitochondrial F1F0 ATP synthase is the key protein that synthesizes ATP molecules through a complex catalytic mechanism. While the nuclear genome encodes the majority of ATP synthase subunits, the mitochondrial genome encodes some of the enzyme's most critical components. The formation of this multi-subunit enzyme is a complex multi-step process regulated at the level of transcription, translation, and assembly. Defects in one or more of these steps can result in decreased ATP...
ATP Synthase: Structure
ATP synthase or ATPase is among the most conserved proteins found in bacteria, mammals, and plants. This enzyme can catalyze a forward reaction in response to the electrochemical gradient, producing ATP from ADP and inorganic phosphate. ATP synthase can also work in a reverse direction by hydrolyzing ATP and generating an electrochemical gradient. Different forms of ATP synthases have evolved special features to meet the specific demands of the cell. Based on their specific feature, ATP...
