alpha-amylase e.c.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as pseudomonas and asperigllus, as well as muscles and ovarian tubes.1.2 alpha-amylase from bacillus subtilis #1024(a tcc 465)* was purified with a highest degree of purity in our laboratory (31.59 u/mg). the extracellular alpha-amylase was subjected to different pu...

The meningococcus cell contains a peptonase enzyme which hydrolyzes the peptides and similar constituents of commercial "peptone." The activity of this enzyme is independent of the presence of the formed bacterial cell. The peptonase enzyme is more resistant to heat and to oxidation than is the maltase enzyme of the same bacteria.

Bacterial enzyme ‘Hyaluronidase’ is a complex polysaccharide degrading enzyme that cleaves â-GlcNAc-(14) glycosidic linkage of Hyaluronate (HA) by â-elimination process. It is synthesized by a spectrum of grampositive bacteria which serve as potential contributors to a multitude of infectious diseases in human beings. Especially, group A streptococcus bacteria (GAS) have evolved several orders...
