The refolding of recombinant human liver methylmalonyl-CoA mutase from inclusion bodies produced in Escherichia coli : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry at Massey University [PDF]
, 1998 Human methylmalonyl-CoA mutase (hMCM) is an adenosylcobalamin-dependent enzyme that catalyses the structural rearrangement of (R)-methylmalonyl-CoA to succinyl-CoA as pan of the catabolism of the branched chain amino acids valine, leucine and isoleucine,

An Expanded Mechanism for Rhodanese Catalysis
Journal of Biological Chemistry, 1974 Abstract The kinetic behavior of rhodanese (thiosulfate:cyanide sulfurtransferase, EC 2.8.1.1) was investigated at pH values from 5.0 to 10.8. The binding of thiosulfate was shown to be dependent upon a pK' of 9.9, with the protonated enzyme binding the substrate much more strongly than the deprotonated form. An enzymic nucleophile displaces sulfite to

Biological hydropersulfides and related polysulfides – a new concept and perspective in redox biology [PDF]
, 2018 The chemical biology of thiols (RSH, e.g., cysteine and cysteine‐containing proteins/peptides) has been a topic of extreme interest for many decades due to their reported roles in protein structure/folding, redox signaling, metal ligation, cellular ...

Supersulfide biology and translational medicine for disease control
British Journal of Pharmacology, Volume 183, Issue 1, Page 115-130, January 2026.Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

Kinetic properties of Rhodanese from African locust bean seeds (Parkia biglobosa)
Asian Journal of Biomedical and Pharmaceutical Sciences, 2019 African locust bean (Parkia biglobosa) is a legume which can be processed into condiment. Rhodanese is a sulphurtransferase enzyme. It catalyses the degradation of cyanide to a less toxic metabolite, thiocyanate.

Bovine mitochondrial rhodanese is a phosphoprotein
Journal of Biological Chemistry, 1989 The mitochondrial sulfurtransferase, rhodanese, has been analyzed for phosphate content. Significant amounts of protein-bound phosphate (30-40%) were measured in the six rhodanese preparations examined. Chromatographic experiments followed by phosphate analyses done on two of the preparations indicated that rhodanese A and rhodanese B, two enzyme forms

Physicochemical properties of rhodanese from the kidney of cane rat (Thryonomys swinderianus)
African Journal of Biotechnology, 2019 We report the properties of partially purified rhodanese, a cyanide detoxifying enzyme isolated from the kidney of the greater cane rat commonly known as grasscutter (Thryonomys swinderianus). T. swinderianus kidney rhodanese had a specific activity of 1.

Bioleaching Microbial Community Metabolism and Composition Driven by Copper Sulphide Mineral Type
Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.Bioleaching is a microbially mediated green technology for the recovery of metals from ore. Here, microbial consortia from a copper bioleaching column in Cyprus were cultivated on chalcopyrite (CuFeS2) and then sub‐cultured on chalcocite (Cu2S) and chalcopyrite to investigate how mineral type and surface chemistry influence microbial community ...
