Applied SciencesHyaluronan (HA) is a ubiquitous macromolecule in the human body with remarkable structure and function. HA presents a key role in several biological processes in mammals. The synthesis/catabolism of HA is critical in several pathologies and has been used

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 ...

Molecular Weight of Malt-Amylase [PDF]
Nature, 1948 IN an earlier investigation1, the molecular weight of α-amylase from pig‘s pancreas2,3 Was found to be 45,000, as calculated from the values4 s20 = 4·50 S, D = 8·05 × 10-7 C.G.S. and V20 = 0·70. At this Institute a new method for the isolation of amylase from malt has been developed5.

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability
FEBS Letters, EarlyView.Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

High-molecular-weight subunits of wheat glutenin
, 1992 The high molecular weight (HMW) subunits of wheat glutenin are of considerable interest because of their relationship to breadmaking quality. We review recent studies of their genetics, amino acid sequences and conformations, and discuss how they may be ...
