Purification and characterization of an acidic, thermophilic phytase from a newly isolated Geobacillus stearothermophilus strain DM12
Microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. In addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. Bacillus sp. DM12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...
متن کاملPurification and partial characterization of the nephritis strain- associated protein from Streptococcus pyogenes, group A
We report the isolation and purification of the nephritis strain-associated protein (NSAP) first described by Villareal et al. (8). Amino acid analysis, and determination of the first 21 amino-terminal amino acids indicated that this 46 kD protein is a streptokinase. Biochemical analysis confirmed that NSAP could act as a plasminogen activator; immunological investigations indicated that NSAP i...

متن کاملPurification of endopeptidase-24.11 ('enkephalinase') from pig brain by immunoadsorbent chromatography.
Membrane preparations from striatum of pig brain contain endopeptidase activity towards iodoinsulin B-chain. Only 50% of the hydrolysis of insulin B-chain is inhibitable by phosphoramidon, and DEAE-cellulose chromatography can resolve the phosphoramidon-sensitive and -insensitive activities. The former activity (now designated 'endopeptidase-24.11') is responsible for hydrolysis of [D-Ala2,Leu5...
متن کاملFibronectin binding to a Streptococcus pyogenes strain.
In previous studies, Staphylococcus aureus has been shown to bind fibronectin (P. Kuusela, Nature (London) 276:718-720, 1978), an interaction that may be important in bacterial attachment and opsonization. Recently some strains of streptococci of serological groups A, C, and G were also found to bind fibronectin. The binding to one selected strain of Streptococcus pyogenes has been characterize...
