Croatian Journal of Food Science and Technology, 2018 Rose hips (Rosa canina L.) and Cornelian cherry (Cornus mas L.) seeds are waste products from the manufacture of juice, syrup, puree, jams or wines and as such, they contain significant amount of oil. Special emphasis in the last few decades is given to “

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Extraction of Amino Acid Esters Using a Pillar[6]arene Carboxylic Acid Derivative as a Novel Acidic Macrocyclic Compound [PDF]
Pillararenes are a series of novel macrocyclic compounds discovered in the 2000s. However, solvent extraction based on ion exchange using pillararene derivatives is currently limited. Recently, a pillar[6]arene hexaacetic acid derivative (OctP[6]CH2COOH)

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
