Faecal proteinases of the fungus-growing ant, Atta texana: Properties, significance and possible origin
(Elsevier, 1975-10)
The proteolytic activity previously reported in the faecal fluid of fungus-growing ants is due to the presence of three enzymes. These enzymes have been partially purified and characterized. One is a serine proteinase; the ...
An idealized concept of the true cladistic character
(Elsevier, 1975-04)
Estimating evolutionary relationships is basic to the objectives of systematics. Comparative data, structured as taxonomic characters, are usually the essential considerations on which such estimates are founded. Some ...
Effects of activity and temperature on aerobic and anaerobic metabolism in the Galapagos marine iguana
(Springer-Verlag, 1975-12)
1 Standard and maximal levels of oxygen consumption, and lactate production during burst activity were determined in the Galapagos marine iguana, Amblyrhynchus cristatus . This semiaquatic lizard sustains vigorous activity ...
Faecal proteinases of the fungus-growing ant, Atta texana: Their fungal origin and ecological significance
(Elsevier, 1975-11)
The fluid contained within the mycelium of the fungus cultured by the attine ant, Atta texana, contains three proteolytic enzymes. One enzyme is a DFP-sensitive alkaline proteinase; the other two are metal-chelator-sensitive ...
Activity of faecal fluid of a leaf-cutting ant toward plant cell wall polysaccharides
(Elsevier, 1975-12)
The faecal fluid of the leaf-cutting ant, Atta colombica tonsipes, has been shown to contain enzymes active in the degradation of pectin, sodium polypectate, xylan, and carboxymethylcellulose. In addition, glycosidase ...
