TRANSFER OF PYRIDOXAL 5'-PHOSPHATE FROM ALBUMIN-PYRIDOXAL 5'-PHOSPHATE COMPLEX TO APO-ASPARTATE AMINOTRANSFERASE

Journal of Nutritional Science and Vitaminology, 1973
Pyridoxal 5'-phosphate(PLP)is known to combine with bovine serum albumin to form a (1:1) complex which scarcely dissociates, even when subjected to intensive dialysis. When this complex was incubated with apo-aspartate aminotransferase (apoCOT)for an appropriate time and the preincubated mixture then submitted to the usual GOT assay, the appearance of ...

Protective role of vitamin B6 (PLP) against DNA damage in Drosophila models of type 2 diabetes [PDF]

, 2018
Growing evidence shows that improper intake of vitamin B6 increases cancer risk and several studies indicate that diabetic patients have a higher risk of developing tumors.

Identification of YbhA as the pyridoxal 5'-phosphate (PLP) phosphatase in Escherichia coli: Importance of PLP homeostasis on the bacterial growth.

Journal of General and Applied Microbiology, 2018
The gene ybhA of Escherichia coli encodes a phosphatase that has an in vitro specificity to dephosphorylate pyridoxal 5'-phosphate (PLP or vitamin B6), a co-factor for aminotransferases and other enzymes. In this study, we found that excess pyridoxal (PL)

Comparing the sensitivity of pyridoxal-5-phosphate, homocysteine and neopterin in coronary heart disease

Pteridines, 2002
Blood serum pyridoxal-5-phosphate, homocysteine and neopterin concentrations have been examined in 30 healthy individuals and 87 patients with coronary heart disease, verified by coronary angiography.

It takes two to tango: defining an essential second active site in pyridoxal 5'-phosphate synthase. [PDF]

PLoS ONE, 2011
The prevalent de novo biosynthetic pathway of vitamin B6 involves only two enzymes (Pdx1 and Pdx2) that form an ornate multisubunit complex functioning as a glutamine amidotransferase.

Crystal structure of L-aspartate aminotransferase from Schizosaccharomyces pombe.

PLoS ONE, 2019
L-aspartate aminotransferase is a pyridoxal 5'-phosphate-dependent transaminase that catalyzes reversible transfer of an α-amino group from aspartate to α-ketoglutarate or from glutamate to oxaloacetate.

Structural Basis of the Substrate Specificity and Enzyme Catalysis of a Papaver somniferum Tyrosine Decarboxylase

Frontiers in Molecular Biosciences, 2017
Tyrosine decarboxylase (TyDC), a type II pyridoxal 5′-phosphate decarboxylase, catalyzes the decarboxylation of tyrosine. Due to a generally high sequence identity to other aromatic amino acid decarboxylases (AAADs), primary sequence information is not ...

A novel synthesis of pyridoxal-5'-phosphate.

Agricultural and Biological Chemistry, 1977
Pyridoxal-5′-phosphate was synthesized in excellent yield by phosphorylation of 1-secondaryammo-l,3-dihydro-7-hydroxy-6-methyl-furo(3,4-c)pyridine which was readily obtained by a condensation reaction between pyridoxal and a secondary amine.

A loss of Pdxk model of Parkinson disease in Drosophila can be suppressed by Buffy

BMC Research Notes, 2017
Background The identification of a DNA variant in pyridoxal kinase (Pdxk) associated with increased risk to Parkinson disease (PD) gene led us to study the inhibition of this gene in the Dopa decarboxylase (Ddc)-expressing neurons of the well-studied ...
