===BOVINE ENDOTHELIAL NITRIC OXIDE SYNTHASE, ETHYL-ISOSELENOUREA COMPLEX===

~~==Overview==~~

<!--

~~Analyzing the active site topology and plasticity of nitric oxide synthase (NOS) and understanding enzyme~~-~~drug interactions are crucial for the development of potent, isoform~~-selective NOS inhibitors. A small hydrophobic pocket in the active site is identified in the bovine eNOS heme domain structures complexed with potent isothiourea inhibitors: seleno analogue of S-ethyl-isothiourea, ~~S-isopropyl-isothiourea, and 2-aminothiazoline~~, ~~respectively. These structures reveal~~ the ~~importance of nonpolar van der Waals contacts in addition~~ to the ~~well-known hydrogen bonding interactions between inhibitor and enzyme~~. ~~The scaffold of a potent NOS inhibitor should be capable of donating hydrogen bonds to as well as making nonpolar contacts with amino acids in~~ the ~~NOS active site~~.

The line below this paragraph, {{ABSTRACT_PUBMED_11051558}}, adds the Publication Abstract to the page

(as it appears on PubMed at http://www.pubmed.gov), where 11051558 is the PubMed ID number.
