Purification and properties of P-4503b, a constitutive form of cytochrome P-450, from rabbit liver microsomes
(Elsevier, 1979-12-14)
This laboratory has previously reported the occurrence in rabbit liver microsomes of a non-inducible form of cytochrome P-450, designated P-4503b because of its electrophoretic mobility relative to that of phenobarbital-inducible ...
Analysis of HGPRT − CRM + human lymphoblast mutants
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1979-11)
Three 6-thioguanine-resistant mutants of the human diploid lymphoblast line MGL-8 were studied. The inactivation by heat of both HGPRT activity and antigenicity of the HGPRT immunologically cross-reacting material of the ...
Raman spectrum of protocatechuate dioxygenase from Pseudomonas putida new low frequency bands
(Elsevier, 1979-04-13)
The Raman spectrum (441.6 nm excitation) of protocatechuate 3,4-dioxygenase (PCD) from Pseudomonas putida shows resonance enhanced bands at 1605, 1504, 1270, 858, and 830 cm-1 which are due to the p-hydroxyphenyl group of ...
Role of a hydrophobic polypeptide in the N-terminal region of NADPH-cytochrome P-450 reductase in complex formation with P-450
(Elsevier, 1979-12-28)
Detergent-solubilized liver microsomal NADPH-cytochrome P-450 reductase is known to retain the ability to catalyze electron transfer to cytochrome P-450, whereas the trypsin-solubilized reductase does not. In the present ...
Central projections of fibers in the auditory and tensor nerves of cicadas (Homoptera: Cicadidae)
(Springer-Verlag, 1979-11)
The auditory and tensor nerves of cicadas are mixed nerves containing both afferent and efferent elements. In 17-year cicadas, and in Okanagana rimosa , the auditory nerve contains afferents from body hairs, from the ...
Reconstitution of cyanobacterial photophosphorylation by a latent Ca+2-ATPase
(Elsevier, 1979-10-12)
Photosynthetic membranes derived from sonic extracts of the cyanobacterium contain a latent Ca+2-ATPase which is activated by exposure to trypsin. When sonic membranes are washed with ethylenediaminetetraacetic acid, the ...
Bootstrapping on the adaptive landscape
(Elsevier, 1979-08)
Different versions of a gene or of a multigenic system may be essentially equivalent so far as the specific function of the structures which they code for or control is concerned, but very different with respect to their ...
Feedforward inhibition in biosynthetic pathways: inhibition of the aminoacyl-tRNA synthetase by the penultimate product
(Elsevier, 1979-04-21)
Inhibition of the aminoacyl-tRNA synthetase by the penultimate product of a pathway for the biosynthesis of an amino acid has been reported for several pathways in many different types of organisms. A regulatory role for ...
Viroplasm and large virus-like particles in the dinoflagellate Gymnodinium uberrimum
(Springer-Verlag, 1979-09)
Virus-like particles (VLPs) measuring 385±5 nm in diameter are described in the freshwater dinoflagellate Gymnodinium uberrimum . The VLPs are found in association with, and “budding” from a vesicular viroplasmic area. A ...
