Cloning and Characterization of Pyridoxal Kinase from Geobacillus sp. H6a

Journal of Pure and Applied Microbiology, 2022
Pyridoxal kinase encoded by pdxK gene, is the important key enzyme in the salvage pathway of vitamin B6 biosynthesis. The enzyme catalyzes the phosphorylation of the 5′ alcohol groups of free form vitamin B6 into their 5′-phosphate forms that requires ...

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 ...
