The increase in surface electronegativity of the cyclic nucleotide binding sites may either be a reflection of an overall conformational change due to

Human Nature, Global War and Justice, adenosine, no good antagonists of P.-purinergic receptors are available, and cell surface hydrolases readily metabolize ATP and ADP to adenosine, which can then produce physiological effects through P.-purinergic receptors. However, the development of relatively non-hydrolyzable analogs of ATP help

Some of these G-proteins are apparently widely distributed in different cell types of the mammalian

When CheY is phosphorylated it modulates bacterial flagellar rotation and thus effects the cells’ movement. When CheB is phosphorylated it increases its ability to modify the cell surface receptor
