Naturally Occurring Protein Crystals in the Potato

Naturally occurring protein crystals in the potato : inhibitor of papain, chymopapain, and ficin.

Protein crystals isolated from potato tubers were found to consist of a proteinase inhibitor active against the cysteine proteinases papain, chymopapain, and ficin. The molecular weight as determined by gel filtration at pH 4.3 or by gel electrophoresis in the presence of dodecylsulfate was 80 kilodaltons. When the inhibitor was evaluated at pH 8.4 in a linear concentration (4-30% polyacrylamid...

Naturally occurring ehrlichiosis in Egyptian dogs

Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...

Protein stabilization by naturally occurring osmolytes.

Natural selection is believed to be an unforgiving and relentless force in the evolution of life on earth. An organism that cannot adapt to a changing environment or an environment hostile to cell functions is at risk as a species. So it is important to understand the mechanisms used by plants, animals, and microorganisms in adapting to environments in the biosphere that would ordinarily denatu...

Concerning the Naturally Occurring Porphyrins

Evidence for a dualism of the porphyrins in nature has been repeatedly presented by Hans Fischer (1, 2, 3). This means that both plant and animal organisms are capable of the formation of porphyrins of two isomeric series, those corresponding to aetioporphyrin III, including hemoglobin and chlorophyll, and those of the aetioporphyrin I type, the function of whose representatives is as yet very ...
