Modulation of glucan-enzyme interactions by domain V in GTF-SI from Streptococcus mutans
(2019)
Glucansucrase GTF-SI from Streptococcus mutans is a multidomain enzyme that catalyzes the synthesis of glucan polymers. Domain V locates 100 angstrom from the catalytic site and is required for an optimal activity. ...
A novel activating effect of the regulatory subunit of protein kinase A on catalytic subunit activity
(Elsevier Science Inc, 2008-12)
The strength of the interaction between the catalytic and regulatory subunits in protein kinase A differs among species. The linker region from regulatory subunits is non-conserved. To evaluate the participation of this ...
A new approach to obtain the catalytic site of human Angiotensin Converting Enzyme
(European Society of Biochemical Engineering Sciences - ESBES, 2019)
Catalytic and glycan-binding abilities of ppGalNAc-T2 are regulated by acetylation
(Academic Press Inc Elsevier Science, 2011-06)
Post-translational acetylation is an important molecular regulatory mechanism affecting the biological activity of proteins. Polypeptide GalNAc transferases (ppGalNAc-Ts) are a family of enzymes that catalyze initiation ...
Family 1 carbohydrate binding-modules enhance saccharification rates
(SpringerOpenHeidelberg, 2014-04)
Cellulose degrading enzymes usually have a two-domain structure consisting of a catalytic domain and a non-catalytic carbohydrate-binding module. Although it is well known the importance of those modules in cell wall ...
Characterization and catalytic evaluation of aluminum oxides obtained by the atrane route
(Elsevier Science, 2011-05)
The atrane route (aluminum tri-sec butoxide as the metal source mixed with tri-ethanolamine to yield the alumatrane complex) was used to synthesize aluminas that showed specific surface areas in the 150-275 m2/g range and ...
Crystallization and preliminary diffraction analysis of the catalytic domain of major extracellular endoglucanase from Xanthomonas campestris pv. campestris
(International Union of Crystallography - IUCrChester, 2013-02)
Cellulases, such as endoglucanases, exoglucanases and β-glucosidases, are important enzymes used in the process of enzymatic hydrolysis of plant biomass. The bacteria Xanthomonas campestris pv. campestris expresses a large ...
Purification, crystallization and preliminary crystallographic analysis of the catalytic domain of the extracellular cellulase CBHI from Trichoderma harzianum
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
The filamentous fungus Trichoderma harzianum has a considerable cellulolytic activity that is mediated by a complex of enzymes which are essential for the hydrolysis of microcrystalline cellulose. These enzymes were produced ...
