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

open access: yesFrontiers 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 ...

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

open access: yesPLoS 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.

The Human SLC25A33 and SLC25A36 Genes of Solute Carrier Family 25 Encode Two Mitochondrial Pyrimidine Nucleotide Transporters [PDF]

open access: yes, 2014
The human genome encodes 53 members of the solute carrier family 25 (SLC25), also called the mitochondrial carrier family, many of which have been shown to transport inorganic anions, amino acids, carboxylates, nucleotides, and coenzymes across the inner

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Pyridoxal 5′-Phosphate-dependent Catalytic Antibody [PDF]

open access: yesJournal of Biological Chemistry, 1996
Cofactors might efficiently extend the catalytic potential of antibodies. Monoclonal antibodies against Nalpha-phosphopyridoxyl-L-lysine were screened for: 1) binding of 5'-phosphopyridoxyl amino acids, 2) binding of Schiff base of pyridoxal 5'-phosphate (PLP) and amino acids, the first intermediate of all PLP-dependent reactions, and 3) catalysis of ...
