A multiplicity of miscellaneous type neurotoxins were detected in the venom of the cobra Naja naja naja by use of reverse-phase HPLC and FPLC. The primary structures of major forms were determined, giving 4 novel structures. All four contain 62-65 residues, with 10 half-cystine residues and resemble the miscellaneous type of toxins from other Naja species. Differences within the species are extensive,...
Stomach aldehyde dehydrogenase was structurally evaluated by analysis of peptide fragments of the human enzyme and comparisons with corresponding parts from other characterized aldehyde dehydrogenases. The results establish a large part of the structure, confirming that the stomach enzyme is identical to the inducible or tumor-derived dimeric aldehyde dehydrogenase. In addition, species variations...
