Cellodextrin Metabolism and Phosphotransferase System‐Catalyzed Uptake in Enterococcus faecalis

Molecular Microbiology, Volume 123, Issue 4, Page 378-391, April 2025.
In an infectious context, β‐glucoside metabolism is highly induced in Enterococcus faecalis. Our work demonstrates that this bacterium possesses a network of multiple PTS transporters dedicated to the transport of cellobiose and cellodextrins. The genes encoding the proteins involved in this metabolism are clustered within a single locus in the E ...

Transcriptomic and Proteomic Response to Grain Filling Reveal Potential Grain Size Regulation Mechanisms in Quinoa (Chenopodium quinoa Willd)

Plant Breeding, EarlyView.
ABSTRACT Grain size is an important factor affecting quinoa yield, and studying the molecular mechanism of quinoa grain size formation is of great significance for cultivar selection. In this study, we analysed phenotypic traits, conducted RNA sequencing and proteomic detection during grain filling in different developmental stages.

Nucleotide sequence of arfB of Clostridium stercorarium, and prediction of catalytic residues of alpha-L-arabinofuranosidases based on local similarity with several families of glycosyl hydrolases.

FEMS Microbiology Letters, 1998
The nucleotide sequence of the alpha-L-arabinofuranosidase gene arfB from Clostridium stercorarium was determined. The deduced protein has a molecular mass of 56.2 kDa with an amino terminus identical to the N-terminal sequence of the purified mature ...

Light‐Driven Transcriptomic Changes in Monilinia fructigena During Early Infection of Nectarines

Plant Pathology, EarlyView.
White light triggers transient gene activation in Monilinia fructigena, but prolonged exposure to it suppresses some virulence‐related genes. ABSTRACT Brown rot is a fungal disease affecting stone fruit crops worldwide, whose main causal agents are Monilinia fructicola, M. laxa and M. fructigena in Spain. However, M. fructicola and M.

Intricate Knots in Proteins: Function and Evolution [PDF]

P. Virnau, L. A. Mirny, M. Kardar, PLoS Comp Biol 2, 1074-1079 (2006), 2007
A number of recently discovered protein structures incorporate a rather unexpected structural feature: a knot in the polypeptide backbone. These knots are extremely rare, but their occurrence is likely connected to protein function in as yet unexplored fashion.

A hydrophobic platform as a mechanistically relevant transition state stabilising factor appears to be present in the active centre of all glycoside hydrolases [PDF]

, 2003
An in silico survey of the −1 subsite of all known 3D-structures of O-glycoside hydrolases containing a suitably positioned ligand has led to the recognition – apparently without exceptions – of a transition state stabilising hydrophobic platform which ...

Chitotriosidase, a chitinase, and the 39-kDa human cartilage glycoprotein, a chitin-binding lectin, are homologues of family 18 glycosyl hydrolases secreted by human macrophages.

European Journal of Biochemistry, 1998
In various mammals, enzymatically active and inactive members of family 18 glycosyl hydrolases, containing chitinases, have been identified. In man, chitotriosidase is the functional chitinolytic enzyme, whilst the homologous human cartilage 39-kDa ...

Genetic and transcriptomic analysis of lentil seed imbibition and dormancy in relation to its domestication

The Plant Genome, Volume 18, Issue 2, June 2025.
Abstract Seed dormancy is an adaptation that delays germination to prevent the start of this process during unsuitable conditions. It is crucial in wild species but its loss was selected during crop domestication to ensure a fast and uniform germination. Water uptake, or imbibition, is the first step of germination.

Variant filters using segregation information improve mapping of nectar‐production genes in sunflower (Helianthus annuus L.)

The Plant Genome, Volume 18, Issue 2, June 2025.
Abstract Accurate variant calling is critical for identifying the genetic basis of complex traits, yet filters used in variant detection may inadvertently exclude valuable genetic information. In this study, we compare common sequencing depth filters, used to eliminate error‐prone variants associated with repetitive regions and technical issues, with a
