[Incorporation of low molecular SH-containing compounds in nitrosyl complexes of nonheme iron in cell-free and cell preparations].
It has been shown that the endogenic low molecular SH-containing compounds in non-cellular liver and yeast preparates include in nitrosyl non-haem iron complexes at basic pH and in result of addition of iron salts into these preparates. The content of nitrosyl non-haem complexes with SH-containing low molecular compounds is not more than 0,5-1% of the quantity of identical non-haem iron complexes with RS-groups of proteins. The low content of these complexes appear to be due to as the low content of low molecular compounds with ionized RS-groups as the competitive action and RS-groups of proteins for iron and NO.
