Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Homology of the NifS family of proteins to a new class of pyridoxal phosphate-dependent enzymes

, 1993
Iterative profile sequence analysis reveals a remote homology of peroxisomal serine-pyruvate aminotransferases from mammals to the small subunit of soluble hydrogenases from cyanobacteria, an isopenicillin N epimerase, the NifS gene products from ...

Racemisation of Amino Acids: From Synthetic Challenge to Biological Significance

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Racemisation, once considered an undesirable synthetic side reaction, also occurs naturally in amino acids and influences biological processes. Evidence links stereochemical conversion to ageing, protein turnover, and cellular development. This review examines mechanisms, control strategies in synthesis, applications and implications in physiology ...

Trypanosoma brucei brucei:uptake and metabolism of pyridoxine and pyridoxal

, 1995
The uptake and metabolism of the B6 vitamers pyridoxine and pyridoxal by T. brucei (TREU 55) was investigated. The results show that these vitamers are taken up by simple diffusion followed by metabolic trapping.

Serine hydroxymethyltransferase from mung bean (Vigna radiata) is not a pyridoxal-5′-phosphate-dependent enzyme

, 1991
Serine hydroxymethyltransferase from mammalian and bacterial sources is a pyridoxal-5′-phosphate-containing enzyme, but the requirement of pyridoxal-5′-phosphate for the activity of the enzyme from plant sources is not clear.

Metabolism of [14C]- and [32P]Pyridoxal 5-Phosphate and [3H]pyridoxal Administered Intravenously to Pigs and Goats

, 1992
To gain more information about the kinetics of vitamin B-6 metabolism in vivo, the metabolism of tracer was examined after the simultaneous intravenous administration of [32P] and [14C]pyridoxal phosphate and [3H]pyridoxal in two 93-kg pigs and two 60-kg

Modification of brain glutamate dehydrogenase isoproteins with pyridoxal 5′-phosphate

, 1996
Two soluble forms of brain glutamate dehydrogenase isoproteins were inactivated by pyridoxal 5′-phosphate. Restoration of catalytic activity can be accomplished by dialysis and addition of an excess of cysteine or lysine.
