The metabolism of the insecticide carbaryl (1-naphthyl N-methylcarbamate) by fat body of the blowfly larva Calliphora erythrocephala.

Purification and characterization of the N-methylcarbamate hydrolase from Pseudomonas strain CRL-OK.

A unique cytosolic enzyme that hydrolyzes the carbamate linkage of the insecticide carbaryl (1-naphthyl N-methylcarbamate) was purified from extracts of Pseudomonas sp. strain CRL-OK. Substrates of the hydrolase include the N-methylcarbamate pesticides carbofuran and aldicarb but not the phenylcarbamate isopropyl m-chlorocarbanilate, the thiocarbamate S-ethyl N,N-dipropylthiocarbamate, or the d...

The Internal Secretion of Protease by the Salivary Gland of the Larva of the Blowfly Calliphora erythrocephala

high correlation (r 0.89); the corresponding value for the colorimetric method was r 0.70. A highly significant correlation (r -0.97) between pyruvate (P,) and the olfactory threshold concentration of onion juice has been observed by Schwimmer & Guadagni (1962). The importance of thiolsulphinate as an unstable intermediate in the production of the components of onion that contribute to its flav...

An electron diffraction study of the crystalline structure of the lipids in the pupal excuviae of Calliphora erythrocephala.

Electron diffraction techniques have been extensively used for the direct crystallographic examination of thin films of fatty materials, but they have hitherto not been applied to the study of natural membranes. These techniques provide more information than diffraction of X-rays about the atomic and molecular organization of surface structures. X-ray diffraction methods have been used successf...
