Structural and functional studies on Salmonella typhimurium pyridoxal kinase: the first structural evidence for the formation of Schiff base with the substrate.

A large number of enzymes depend on the ubiquitous cofactor pyridoxal 5' phosphate (PLP) for their activity. Pyridoxal kinase (PLK) is the key enzyme involved in the synthesis of PLP from the three forms of vitamin B via the salvage pathway. In the present work, we determined the unliganded structure of StPLK in a monoclinic form and its ternary complex with bound pyridoxal (PL), ADP and Mg in two different tetragonal crystal forms (Form I and Form II).

Guillain-Barré syndrome in a patient with neuropsychiatric systemic lupus erythematosus.

Guillain-Barré syndrome is a rare manifestation of neuropsychiatric systemic lupus erythematosus (SLE). Clinical and electrophysiological features of Guillain-Barré syndrome in patients with SLE are different from those in patients without SLE. There is considerable variation in the management and prognosis.

Application of PCR fingerprinting using (GACA)4 primer in the rapid discrimination of dermatophytes.

Background: Superficial fungal infections have a major impact on cosmetic health, affecting more than 20-25% of the global population, which is predominantly caused by dermatophytes. As per literature search, molecular strain typing of dermatophytes has not been investigated in India. Therefore, the present study was carried out to characterise the dermatophyte species and strains by molecular methods.

Successful data recovery from oscillation photographs containing strong polycrystalline diffraction rings from an unknown small-molecule contaminant: preliminary structure solution of Salmonella typhimurium pyridoxal kinase (PdxK).
