RNA 3′-phosphate cyclase (RtcA) synthesizes RNA 2′,3′ cyclic phosphate ends via three steps: reaction with ATP to form a covalent RtcA-(histidinyl-Nε)-AMP intermediate; transfer of adenylate to an RNA ...
ATP splitting: The transport protein MsbA (grey) splits ATP (coloured), to generate energy for the transport process. ATP has three phosphate groups (orange-red). If one of them is split off (yellow), ...
For 50 years, thousands of labs around the world have studied cells' critical internal communications, and scientists had assumed the speakers were known. But now, in the Dec. 17 issue of Science, ...
The ATP:D-fructose-6-phosphate 1-phosphotransferase (PFK) from Selenastrum minutum was purified to homogeneity. The purified plastid enzyme had a specific activity of 180 micromoles per milligram of ...
Adenosine triphosphate (ATP) is a key molecule which upon hydrolysis provides energy to facilitate a variety of cellular processes that are essential for life. The cell utilizes the energy of ATP ...
Scientists in Boston may have solved a longstanding mystery – how early life developed on an Earth where phosphate, a chemical so vital to a vast range of biological processes today, was unavailable.
While conducting an otherwise straightforward investigation into the assembly mechanism of calcium-phosphate clusters, researchers at UC Santa Barbara and New York University (NYU) made a surprising ...
How a transport protein obtains its driving force from the energy storage molecule ATP, has been tracked dynamically. Using time-resolved infrared spectroscopy, they measured the structural changes in ...
Tracked step for step ATP splitting in membrane protein dynamically measured for the first time RUB researchers report in the Journal of Biological Chemistry How a transport protein obtains its ...
