Peptides present in the skin secretion of the South African frog, Xenopus laevis, have been
analysed by fast atom bombardment mass spectrometry and hplc in the mass range 500 …

The amino acid sequence of endothiapepsin, the aspartic protease from Endothia parasitica
has been determined. The enzyme consists of 330 residues. The sequence determination …

The isolation of the 26 CNBr fragments from the identical Mr= 180,000 subunits of human
alpha 2-macroglobulin is described. The fragments have been purified by combinations of …

Some properties of the crude lyophilized fibrinolytic enzyme produced by Cochliobolus
lunatus in surface culture were studied. Enzyme concentrations over the range from 0.16 to …

Human pepsinogen A3 and A5 have been purified to chromatographic and electrophoretic
homogeneity. At pH 2 pepsinogen A3 activates at a much faster rate than pepsinogen A5 …

An endopeptidase was partially purified from the fruiting bodies of Tricholoma columbetta.
The enzyme, MW ca 14 500, pH optimum 7.0, hydrolyses the natural substrates, casein and …

1. Conditions were established for growth of mycelial cultures of Armillaria mellea such that
the production of its lysine-specific proteinase was maximized. Proteinase synthesis was …

The proteinase fromArmillaria mellea showed no activity towards the low molecular weight
substratesN-acetylglycyl-l-lysinemethyl ester, N-α-toluenesulphonyl-l-lysinemethyl ester …
