Applicazioni

L-Tyrosine decarboxylase apoenzyme from Streptococcus faecalis has been used:
  • in a study to purify and characterize tyrosine decarboxylase and aromatic-L-amino-acid decarboxylase[1]
  • in a study to investigate the stereospecificity of sodium borohydride reduction of tyrosine decarboxylase[2]
  • in protein synthesis studies[3]

Azioni biochim/fisiol

L-Tyrosine Decarboxylase Apoenzyme is an aromatic L-amino acid decarboxylase.[4] The enzyme activity of tyrosine decarboxylase (TDC) is dependent on the cofactor pyridoxal 5-phosphate (PLP).[5] It catalyzes the decarboxylation of dihydroxyphenylalanine.[4]

Altre note

Dried cells grown on vitamin B6-deficient medium.

Definizione di unità

Sodium boro[3H]hydride reduction of tyrosine decarboxylase from Streptococcus faecalis followed by complete hydrolysis of the enzyme produces epsilon-[3H]pyridoxyllysine. Degradation of this material to [4'-3H]pyridoxamine and stereochemical analysis with apoaspartate aminotransferase shows that the re side at C-4' of the cofactor

Phenolic melanin precursors can be utilized for the development of anti-melanoma agents. The sulphur homologue of tyrosine, 4-S-cysteinylphenol (CP) and its decarboxylation product, 4-S-cysteaminylphenol (CAP) were shown to be substrates of melanoma tyrosinase, forming melanin-like pigment. Both, but in particular
