A multienzyme complex channels substrates and electrons through acetyl-CoA and methane biosynthesis pathways in Methanosarcina.

PLoS ONE, 2014
Multienzyme complexes catalyze important metabolic reactions in many organisms, but little is known about the complexes involved in biological methane production (methanogenesis). A crosslinking-mass spectrometry (XL-MS) strategy was employed to identify

Self-Organization and Chaos in the Metabolism of Hemostasis in a Blood Vessel [PDF]

Ukr. J. Phys., Vol. 61, N 7, p.648-655 (2016), 2017
A mathematical model of the metabolic process of formation of the hemostasis in a blood-carrying vessel is constructed. As distinct from the earlier developed model of the multienzyme prostacyclin-thromboxane system of blood, this model includes, for the first time, the influence of the level of "bad cholesterol", i.e., low-density lipoproteins (LDLs),

The Urea Carboxylase and Allophanate Hydrolase Activities of Urea Amidolyase Are Functionally Independent [PDF]

, 2016
Urea amidolyase (UAL) is a multifunctional biotin-dependent enzyme that contributes to both bacterial and fungal pathogenicity by catalyzing the ATP-dependent cleavage of urea into ammonia and CO2.

Abstract OR-3: Fleeting Ensembles: Transient Protein-Protein Interactions in DNA Repair [PDF]

International Journal of Biomedicine, 2019
Background: DNA repair is a vitally important process that protects the cell’s genome from ongoing damage. Six DNA repair pathways are commonly outlined: direct reversal, base excision repair, nucleotide excision repair, mismatch repair, recombination ...

Characterization of the mycobacterial acyl-CoA carboxylase holo complexes reveals their functional expansion into amino acid catabolism.

PLoS Pathogens, 2015
Biotin-mediated carboxylation of short-chain fatty acid coenzyme A esters is a key step in lipid biosynthesis that is carried out by multienzyme complexes to extend fatty acids by one methylene group.
