Transfer of Sulfur from IscS to IscU during Fe/S Cluster Assembly [PDF]

open access: yes, 2001
The cysteine desulfurase enzymes NifS and IscS provide sulfur for the biosynthesis of Fe/S proteins. NifU and IscU have been proposed to serve as template or scaffold proteins in the initial Fe/S cluster assembly events, but the mechanism of sulfur ...

THE INTERACTION OF PYRIDOXAL PHOSPHATE WITH ALCOHOL DEHYDROGENASE

open access: yesTHE JOURNAL OF VITAMINOLOGY, 1967
The interaction of PAL-P with ADH in vitro was observed, and electrophoretic mobility and absorption spectrum also changed. The molar ratios (PAL-P:ADH) of PAL-P-ADH complex was about 1:9.

Protometabolic functions of pyridoxal: A link between early amino acid synthesis and enzyme evolution

open access: yesThe FEBS Journal, EarlyView.
Schlikker et al. characterized the conversion of pyridoxal to pyridoxamine under conditions mimicking the ones likely existing at the origin of metabolism. These conditions triggered nitrogen incorporation into amino acids in solution before the origins of enzymes.

Manual for starch gel electrophoresis: A method for the detection of genetic variation [PDF]

open access: yes, 1987
The procedure to conduct horizontal starch gel electrophoresis on enzymes is described in detail. Areas covered are (I) collection and storage of specimens, (2) preparation of tissues, (3) preparation of a starch gel, (4) application of enzyme extracts ...

First‐in‐class inhibitors of SbnA reduce siderophore production in Staphylococcus aureus

open access: yesThe FEBS Journal, EarlyView.
The production of the iron‐chelating compound staphyloferrin B by the most invasive S. aureus strains is crucial for colonization, virulence, and survival in the host. Staphyloferrin B biosynthesis is carried out by eight enzymes, the Sbn system, that offer an appealing source of potential targets for the development of antimicrobials.

Influence of Kynurenine, Neopterin, Noradrenaline and Pyridoxal-5-Phosphate on Cholesterol and Phospholipid Content and Phospholipid Biosynthesis in vitro

open access: yesPteridines, 1993
Incorporation of fatty acids into phospholipids has been investigated using samples of rat liver tissue homogenate, Krebs-Ringer-phosphate buffer (pH = 7.4) containing 0.3% albumin, fatty acid mixture and glyceroL The addition of L-kynurenine (4 nmol/g ...

The disease‐linked R336C mutation in cystathionine β‐synthase disrupts communication with the PLP cofactor, yet maintains the enzyme's overall structural integrity

open access: yesThe FEBS Journal, EarlyView.
Cystathionine β‐synthase (CBS) is an essential enzyme involved in cysteine metabolism. The mutation R336C, associated with severe homocystinuria and of high incidence in Qatar, reduces its activity. Our research shows that this mutation does not destabilize the enzyme fold but subtly alters the tautomeric equilibrium of the PLP cofactor within the ...

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

open access: yesBMC 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 ...

Long-term follow-up of an individual with vitamin B6-dependent seizures [PDF]

open access: yes, 1999
We report on a 31-year-old female with vitamin B6-dependent seizures whose seizure onset was in the neonatal period. Her elder brother had the same disorder and died in infancy. Administration of vitamin B6 was initiated in the postnatal period.
