The NO-binding Nitrophorin 1 (NP1), from the saliva of the blood-sucking insect Rhodnius prolixus, contains two diamagnetic FeNO 6 ferrihemes, with i/NO at 1,904 cm-1 and 1,917 cm-1. They exist in a pH-dependent ratio and bind NO reversibly without being reduced. Alternative electronic distribution assignments as FemNO or FenNO+ rely on IR, EPR, NMR, FTIR, and... [Pg.608]

Nitrophorins are haem proteins which are present in the salivary glands of the blood-sucking insect Rhodnius prolixus. Binding of NO to the Fe(III) centre in nitrophorin (NPl) is reversible, and is dependent on pH. Crucial to the process of blood-sucking by Rhodnius prolixus is the fact that NO binds 10 times more tightly at pH 5 (i.e. the pH of the saliva... [Pg.840]

The saliva of blood-sucking insects contains a variety of components that counteract blood clotting and vasoconstriction. A nitric oxide binding heme protein, ni-trophorin 1 (NPl), was studied by UV-vis and FTIR spectroelectrochemistry. In the absence of NO, the spectroelectrochemistry of the Fe / process was clear. However, in the presence of NO, the changes were small for the Fe NO and Fe NO forms, and there was a larger than usual error ( 5 mV rather than 1 to 2 mV) on the redox potentials determined from Nemst plots [246]. [Pg.519]

The nitrophorins comprise a group of, NO transporting proteins found in the saliva of the blood sucking insect Rhodnius prolixus. ssNMR vras employed as an alternative method to gain structural insights on the precipitated protein by Varghese et Using isotopically la-... [Pg.348]

The tropics furnish homes for many types of insects, one of the more interesting of which is euphemistically known as the kissing bug. This bug crawls out of the crevices where it lives so that it can bite humans and suck their blood much like a mosquito. Despite this irritating behavior the bug has redeeming value because of the fascinating chemical tricks it performs. For one thing, as it feeds, it releases its saliva into its victim. The saliva in turn delivers a dose of NO, a molecule that... [Pg.901]
