Substrate-Coenzyme Complex to Tyrosine Decarboxylase
Phosphopyridoxyl derivatives, which are stable analogues of a substrate-coenzyme complex, are bound at the active site with great affinity. From a comparison of the interaction of a number of such compounds with the apoenzyme the AGO values for the binding of the substrate carboxy and phenyl groups and of the coenzyme aldehydic group were determined to be equal to (or more negative than) -3.8,-...

متن کاملTyrosine decarboxylase from Lactobacillus brevis: soluble expression and characterization.
Tyrosine decarboxylase (TDC, EC 4.1.1.25) is an enzyme that catalyzes the decarboxylation of l-tyrosine to produce tyramine and CO2. In this study, a 1881-bp tdc gene from Lactobacillus brevis was cloned and heterologously expressed in Escherichia coli BL21 (DE3). Glucose was discovered to play an important role in the soluble expression of rLbTDC. After optimization, recombinant TDC (rLbTDC) w...
متن کاملTyrosine hydroxylase and DOPA decarboxylase gene variants in personality traits.
Personality influences several characteristics of normal and pathologic behaviors and it is associated with neurotransmitter systems that are under genetic control. The dopaminergic system has been proposed to play a role in the modulation of personality traits. In the present study, variants of the tyrosine hydroxylase (TH) and DOPA decarboxylase (DDC) genes (for TH: rs3842727, rs6356; for DDC...
متن کاملTyrosine Decarboxylase: II. Pyridoxine-deficient Medium for Apoenzyme Production.
Previous communications from this laboratory have established the function of pyridoxine derivatives' in the tyrosine decarboxylase system of Streptococcus faecalis, and a synthetic medium has been described for the production of cells active in this function (Bellamy and Gunsalus, 1943, 1944). Cells grown in media deficient in,pyridoxine derivatives have been shown to contain the tyrosine deca...
