WebThe reduced form of Cys-62 is essential for the DNA binding activity of NF-κB. Several lines of evidence suggest that the redox factor Ref-1 is involved in Cys-62 reduction in the nucleus. We propose that the Ref-1-dependent reduction of p50 in the nucleus is a necessary step for NF-κB activation. WebNov 8, 2005 · Among three mammalian methionine- R -sulfoxide reductases (MsrBs), MsrB1 is a Sec-containing protein, whereas MsrB2 and MsrB3 contain Cys in the active site, making these enzymes an excellent system for addressing the question of why Sec is used in biological systems.

WebJul 26, 2024 · For de novo Cys biosynthesis, firstly, sulfate is reduced to sulfide (S 2−) in most microorganisms in common, and it can be then incorporated into two types of carbon skeleton molecules such as O -acyl- l -serine and O -acyl- l -homoserine to generate organic sulfur molecules, Cys and l -homocysteine (HmCys), respectively. WebNov 28, 2024 · Hydrogen sulfide (H2S) and its bioderivatives analogs, such as L-cysteine (L-Cys) and glutathione (GSH), are ubiquitous biological thiols in the physiological and pathological processes of living systems.
