Yellow and red-violet betalain plant pigments are restricted to several families in the order Caryophyllales, where betacyanins play analogous biological roles anthocyanins. The initial step biosynthesis is hydroxylation of tyrosine form L-DOPA. Using gene expression experiments beets, yeast, Arabidopsis, along with HPLC/MS analysis, present study shows that two novel cytochrome P450 (CYP450) enzymes, CYP76AD6 CYP76AD5, previously described CYP76AD1 can perform this step. Co-expressing these...

Host range is a major determinant in the industrial utility of bacteriophage. A model host permits broad recognition across serovars target bacterium while avoiding cross-reactivity with commensal microbiota. Searching for naturally occurring bacteriophage ideal ranges challenging, time-consuming, and restrictive. To address this, SPTD1.NL, previously published luciferase reporter Salmonella, was used to investigate manipulation through receptor-binding protein engineering. Similar related...

Summary The key enzymatic step in betalain biosynthesis involves conversion of l ‐3,4‐dihydroxyphenylalanine ( ‐ DOPA) to betalamic acid. One class enzymes capable this is 3,4‐dihydroxyphenylalanine 4,5‐dioxygenase DODA ). In betalain‐producing species, multiple paralogs gene are maintained. This study demonstrates which function the pathway and determines residue changes required evolve a betalain‐nonfunctional into betalain‐functional . Functionalities two pairs s were tested by expression...

ABSTRACT Vertebrate fossils have been converted from natural history objects into research specimens through the act of preparation for over 200 years. All basic techniques applied to in 21st Century were already use palaeontological laboratories by first decade 1900s. It behoves any worker field be intimately familiar with processes treatment specimens, as these procedures almost always permanently alter material available interpretation. Historic treatments also complicate attempts...

A reduced mesoporous 5% Pd-YSZ precatalyst was observed to be very active for the Heck reaction providing up 770,000 TON. Three-phase tests have experimentally confirmed that a leached homogeneous species is responsible activity. Residual Pd concentration in solution minimal (<0.10 ppm) and therefore this material has potential applications because it can easily removed by filtration.
