Paper Chromatography as Exemplified by Separation of Urocanic Acid and Deaminohistidine

open access: yesBio-Protocol, 2013
Paper chromatography is an ancient technique to separate low molecular mass compounds based on their distribution between mobile phase (solvent) and stationary phase (cellulose and cellulose-bound water). Paper chromatography has been largely replaced by

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
