Functional metagenomics reveals novel β-galactosidases not predictable from gene sequences. [PDF]

PLoS ONE, 2017
The techniques of metagenomics have allowed researchers to access the genomic potential of uncultivated microbes, but there remain significant barriers to determination of gene function based on DNA sequence alone.

Knockout mutants of Arabidopsis thaliana β-galactosidase. Modifications in the cell wall saccharides and enzymatic activities

Biologia Plantarum, 2018
This work studied the six β-galactosidases (BGALs) of the subfamily a1 of Arabidopsis, that have been proposed to play important roles in the cell wall remodelling during plant development, although their precise functions are still unknown.

β-Galactosidase Deficiency in Colombia

Journal of Inborn Errors of Metabolism and Screening, 2015
β - Galactosidase (BGal) هو أول إنزيم يشارك في تقويض الدهون السفينغولية. ارتبط مرضان بشكل مباشر بنقصه: داء الغانغليوزيدات GM1 و Morquio B. Morquio B هو من بين أندر أنواع داء عديد السكاريد المخاطي (MPS). نهدف إلى توثيق نقص β - galactosidase في كولومبيا. قمنا بتقييم الكريات البيض من 1492 فردًا كولومبيًا أصحاء و 923 مريضًا، تمت إحالتهم بين عام 2005 وأغسطس

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...
