Application

5′-Deoxy-5′-(methylthio)adenosine has been used as a protein methylation inhibitor to reduce E2F transcription factor 1 (E2F1) protein abundance in hepatocellular carcinoma (HCC) cells. It has also been used to inhibit histone methylation modification and study its role in hypoxia inducible factor-1 (Hif-1) nuclear transport.

Biochem/physiol Actions

5′-Deoxy-5′-(methylthio)adenosine (Methylthioadenosine) may be used as a substrate to study the specificity and kinetics of 5′-methylthioadenosinephosphorylase (MTAP) (EC2.4.2.28), a tumor suppressor gene expressed enzyme that supports the S-adenosylmethionine (AdoMet) and methionine salvage pathways.

5'-Methylthioadenosine (MTA) is the common by-product of polyamine (PA), nicotianamine (NA), and ethylene biosynthesis in Arabidopsis (Arabidopsis thaliana). The methylthiol moiety of MTA is salvaged by 5'-methylthioadenosine nucleosidase (MTN) in a reaction producing methylthioribose (MTR) and adenine. The MTN double

Quorum sensing (QS) controls certain behaviors of bacteria in response to population density. In gram-negative bacteria, QS is often mediated by N-acyl-L-homoserine lactones (acyl-HSLs). Because QS influences the virulence of many pathogenic bacteria, synthetic inhibitors of acyl-HSL synthases might be

Functional assignment of uncharacterized proteins is a challenge in the era of large-scale genome sequencing. Here, we combine in extracto NMR, proteomics and transcriptomics with a newly developed (knock-out) metabolomics platform to determine a potential physiological role for a ribulose-1,5-bisphosphate
