Photooxidation of hypotaurine to taurine in the presence of flavins.
TLDR
A new reaction mechanism involving sulfinic radicals on this photochemical reaction is proposed, which was higher at acidic pH and the effectiveness of allyl alcohol as a scavenger pointed to a free-radical mechanism of the reaction.
Ambiguities in the enzymology of sulfur-containing compounds
In the course of this meeting we have occasionally met reactions involving a variety of sulfur-containing compounds carried out by systems or enzymes also used for different purposes. In this final
3-Mercaptopropionate Dioxygenase, a Cysteine Dioxygenase Homologue, Catalyzes the Initial Step of 3-Mercaptopropionate Catabolism in the 3,3-Thiodipropionic Acid-degrading Bacterium Variovorax paradoxus*
TLDR
The hitherto unknown catabolism of 3,3-thiodipropionic acid was elucidated to engineer novel and improved polythioester biosynthesis pathways in the future.
Thiol dioxygenases: unique families of cupin proteins
TLDR
A number of bacterial cupin proteins of unknown function that share low similarity with mammalian CDO and that conserve many residues in the active-site pocket of CDO are identified and a tentative fingerprint motif for ADOs, or DUF1637 family members, is proposed.
Cysteamine Pathway of Taurine Biosynthesis
Three main routes have been discovered in animals able to produce taurine (TAU), called the cysteine sulfinic acid (CSA) pathway, the cysteamine pathway and the inorganic pathway.

TLDR
Of the substrates assayed, only cysteamine is oxidized to the sulfinic derivative in the presence of the cofactor-like compounds named, and the complete amino acid composition has been determined by ion exchange chromatography.

TLDR
Since reduced pyridine nucleotide is not stoichiometrically utilized in the reaction, the reaction appears to be catalyzed by a dioxygenase rather than by two hydroxylases ("mixed function oxidases") acting sequentially.

The role of sulphur, sulphide and reducible dyes in the enzymic oxidation of cysteamine to hypotaurine.
TLDR
It has been found that, when the enzyme is omitted, sulphur and sulphide are able to catalyse the oxidation of cysteamine to cystamine by molecular oxygen.
