Comportamento E a Pele Behavior and the Skin
نویسنده
چکیده
Skinner (1938) once defined behavior as a proper subset of organismic activities—those that involve commerce with the outside world. Here I reexamine and reformulate Skinner’s definition to make the underlying conceptual framework more explicit. This framework turns out to be partly morphological and to rely on biological concepts of organism and adaptation. I propose a reformulation of Skinner’s definition along these lines, and I underscore the importance of the skin, not only in the life of an organism, but in the very definition of its behavior.

متن کاملThe Three-Dimensional Structure of Pectate Lyase E, a Plant Virulence Factor from Erwinia chrysanthemi.
The three-dimensional structure of pectate lyase E (PelE) has been determined by crystallographic techniques at a resolution of 2.2 A. The model includes all 355 amino acids but no solvent, and refines to a crystallographic refinement factor of 20.6%. The polypeptide backbone folds into a large right-handed cylinder, termed a parallel [beta] helix. Loops of various sizes and conformations protr...

Environmental conditions affect transcription of the pectinase genes of Erwinia chrysanthemi 3937.
To depolymerize plant pectin, the phytopathogenic enterobacterium Erwinia chrysanthemi produces a series of enzymes which include a pectin-methyl-esterase encoded by the pem gene and five isoenzymes of pectate lyases encoded by the five genes pelA, pelB, pelC, pelD, and pelE. We have constructed transcriptional fusions between the pectinase gene promoters and the uidA gene, encoding beta-glucur...
