Modeling the architecture of depolymerase-containing receptor binding proteins in Klebsiella phages [PDF]

open access: yes, 2019
Klebsiella pneumoniae carries a thick polysaccharide capsule. This highly variable chemical structure plays an important role in its virulence. Many Klebsiella bacteriophages recognize this capsule with a receptor binding protein (RBP) that contains a ...

Flow injection determination of total catechins and procyanidins in white and red wines [PDF]

open access: yes, 2002
An easily automatable flow-injection (FI) method for the determination of total catechins is reported. The method is based on the reaction of vanillin in acid medium to yield a coloured product with maximum absorption at 500 nm. After optimisation by the
