Substrate Specificity of α-Galactosidase fromAspergillus niger5–16

A Fungal α-Galactosidase from Tricholoma matsutake with Broad Substrate Specificity and Good Hydrolytic Activity on Raffinose Family Oligosaccharides.

An acidic α-galactosidase designated as TMG was purified from the fruiting bodies The purification protocol entailed ion exchange chromatography on Q-Sepharose and of Tricholoma matsutake with 136-fold purification and a specific activity of 909 units/mg. Mono-Q and fast protein liquid chromatography on Superdex 75. TMG is a monomeric protein exhibiting a molecular mass of 47 kDa in SDS-PAGE an...

The Role of Highly Conserved Tryptophan in the Sixth Conserved Region at Substrate Specificity of α- amylase

Early in this study, an α-Amylase from Bacillus megaterium WHO (BMW) was isolated from hot springs of Ramsar (North of Iran), and its gene was cloned in E.coli. Based on its conserved sequence regions and substrate specificity, it was classified as intermediary group enzymes with the specificity of oligo-1,6-glucosidase and neopullulanase subfamilies. In the sixth conserved re...

Novel endo-α-N-acetylgalactosaminidases with broader substrate specificity

In an effort to identify novel endo-alpha-N-acetylgalactosaminidases (endo-alpha-GalNAcases), four potential genes were cloned. Three of the expressed proteins EngEF from Enterococcus faecalis, EngPA from Propionibacterium acnes, and EngCP from Clostridium perfringens were purified and characterized. Their substrate specificity was investigated and compared to the commercially available endo-al...
