GENERAL INFORMATION

COMMENTARY
LITERATURE
malfunction
-
developing stems of transgenic (LuBGAL-RNAi) flax with reduced beta-galactosidase activity have lower concentrations of free Gal and have significant reductions in the thickness of mature cellulosic G-layers compared with controls. Gn-layers, labeled intensively by the galactan-specific LM5 antibody, are greatly expanded in LuBGAL-RNAi transgenic plants. Gross morphology and stem anatomy, including the thickness of bast fiber walls, are otherwise unaffected by silencing of beta-galactosidase transcripts
malfunction
C5VV31
deleting SSU0587 from clinical Streptococcus suis type 2 isolate JX081101 causes a loss of both beta-galactosidase activity and adherence to microvascular endothelial cells
physiological function
-
beta-galactosidase activity is in fact necessary for the dynamic remodeling of polysaccharides that occurs during normal secondary wall development in flax fibers
physiological function
-
mutant PBL2025, that misses 50 genes (SSO3004-3050), including genes coding for a multitude of enzymes possibly involved in sugar degradation or metabolism, is complemented with one of the missing proteins, the beta-galactosidase (SSO3019). The beta-galactosidase complemented strain shows reduced carbohydrate content of the isolated total extracellular polymeric substance implying a role in the modulation of the produced EPS during static biofilm formation
physiological function
C5VV31
the enzyme contributes to bacterial adhesion but not to virulence in mice

patients with type 1 HM1 gangliosidosis (mutation D332N on one allele and mutation S532G on the other allele) have less than 1% residual beta-galactosidase activity and minimal detectable levels of immunoreactive beta-galactosidase protein in fibroblasts. Most of the missense mutations described in GM1 gangliosidosis have little effect on catalytic activity, but do affect protein conformation such that the resulting protein cannot be transported out of the ER and fails to arrive in the lysosome. This accounts for the minimal amounts of the enzyme protein and activity seen in most GM1 gangliosidosis patient fibroblast

during the transglycosylation reaction with lactose of the evolved beta-galactosidases, a major trisaccharide, beta-D-galactopyranosyl-(1-3)-beta-D-galactopyranosyl-(1-4)-D-glucopyranoside (3'-galactosyl-lactose) is formed. At the lactose concentration of 18% (w/v), this trisaccharide is obtained in yields of 11.5% (w/w) with BgaB mutant enzyme R109K, 21% (w/w) with BgaB mutant enzyme R109V, 23% (w/w) with BgaB mutant enzyme R109W, and 2% (w/w) with the wild type BgaB enzyme

quantitative determination of the products of the transglycosylation reactions shows that the amount of glucose is always much higher than that of galactose, which indicates that, during the reaction, galactoside of lactose is used in the transglycosylation reaction to form galactooligosaccharides. Compared to the wild-type enzyme, the yields of galacto-oligosaccharides produced by F441Y and F359Q are increased by 10.8% and 7.4%, respectively
