NCBI and Uniprot Product Information
Uniprot Description
Could be involved in the spore pigmentation and melanin production. Catalyzes the oxidative coupling of 2-aminophenols to form the 2-aminophenoxazinone chromophore. 2-aminophenoxazinone synthesis proceeds via a sequence of three consecutive 2-electron aminophenol oxidations. First, the o-aminophenol is oxidized by two electrons to the quinone imine, which then conjugates to a second o-aminophenol molecule while still bound to the enzyme. This product is further oxidized by two electrons to give rise to the p-quinone imine. The last two steps of the reaction, another conjugation to generate the tricyclic structure and a final two-electron oxidation to yield the 2-aminophenoxazinone product, are thought to be non-enzymatic. It can also uuse 3-hydroxyanthranilic acid (HAA), 4-methyl-3-hydroxyanthranilic acid (MHA), 3,4-dihydroxy-L-phenylalanine (L-DOPA), ferrocyanide and thiophenol as substrates.

Product Notes
The phsA phsa (Catalog #AAA1381326) is a Recombinant Protein produced from E Coli or Yeast or Baculovirus or Mammalian Cell and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Phenoxazinone synthase (phsA), partial, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
