Extracellular purine (ATP, ADP) and pyrimidine (UTP, UDP) nucleotides mediate their effects via P2 receptors (Ralevic and Burnstock, 1998). P2 receptors consist of ligand-gated intrinsic ion channels, ...

Researchers used a novel phosphate-activation reagent, 2-MeImIm-Cl, in an improved coupling reaction to increase the yield of ADP- or ATP-containing molecules. Unlike traditional reactions, the ...

ATP-ADP exchange was estimated in the presence of plasma membrane H+-ATPase of oat (Avena sativa) roots partially purified with Triton X-100 by measuring [14C]ATP formation from [14C]ADP. Most studies ...

In organello starch biosynthesis was studied using intact chloroplasts isolated from spinach leaves (Spinacia oleracea). Immunoblot analysis using a specific antiserum against the mitochondrial ...

A simple two-carbon compound may have been a crucial player in the evolution of metabolism before the advent of cells, according to a new study. The finding potentially sheds light on the earliest ...
