We have employed equilibrium dialysis to help study the mechanism by which the unliganded Escherichia coli trp aporepressor is activated by L-tryptophan to the liganded trp repressor. By measuring the relative affinity of L-tryptophan and various tryptophan analogues for the
In this work we characterize the interaction of cranberry (Vaccinium macrocarpon) proanthocyanidins (PAC) with bovine serum albumin (BSA) and hen egg-white lysozyme (HEL) and determine the effects of these complexes on macrophage activation and antigen presentation. We isolated PAC from
In a previous paper, we demonstrated that the medium-chain fatty acyl-CoA dehydrogenase-catalyzed (MCAD-catalyzed) reductive half-reaction of indolepropionyl-CoA proceeds via formation of a chromophoric intermediary species "X" (absorption maximum = 400 nm) and proposed that the decay of this species might
Shoot branching and growth are controlled by phytohormones such as auxin and other components in Arabidopsis. We identified a mutant (igi1) showing decreased height and bunchy branching patterns. The phenotypes reverted to the wild type in response to RNA interference
An approach to the optimization of product yield in an inducible inclusion body-producing system is presented. Following induction by indoleacrylic acid (IAA) of a trpLE-HIVgp41 fusion protein, we found a large increase in culture turbidity and single-cell dry weight. After
