TL;DR: Guinea-hen egg-white lysozyme was obtained in a chromatographically pure state by ion-exchange chromatography on Amberlite CG-50 by undergoing digestion with trypsin and amino acid sequence was determined chiefly by the Edman dansylation procedure.
53 citations
TL;DR: It is demonstrated by an elegant method (personal communication; to be published) that human leukaemia lysozyme does not show a deletion after residue no. 100 when corn; pared to bird lysozymes.
50 citations
TL;DR: The chemical studies strengthened the view that wax D could be some degradation product of the mycobacterial community, as well as demonstrating a close relationship between the peptidoglycan of an active wax D and the material which constitutes the backbone of myc Cobacterial as wellAs other cell walls.
48 citations
TL;DR: Lysozyme from Nephthys hombergi (Annelid) was obtained in a chromatographically and electrophoretically pure state by gel filtration and ion-exchange chromatography on Amberlite CG-50 and the quantitative amino acid composition, the molecular weight and the N-terminal amino acid of this enzyme are reported.
43 citations
TL;DR: The effect of ketamine on the activity of the laminae IV and V units was studied in spinal cats, and it is found that this effect is not sufficient to explain the whole analgesic action of ketamines and other sites of action must be found, sppecially at the subcortical and cortical levels.

TL;DR: In this paper, the basic concepts and ideas that arise in the theory of shocks with a simple mathematical model related to a single conservation law are introduced. But the analysis is restricted to the case of classical gas dynamics and magneto fluid dynamics.
Abstract: Publisher Summary The chapter presents a local study of shock waves, introducing the basic concepts and ideas that arise in the theory of shocks with a simple mathematical model related to a single conservation law. The study emphasizes on shock relations for a physical phenomenon governed by conservation laws and the classification of shocks. The chapter provides examples in some detail, in particular taken from classical gas dynamics and magneto fluid dynamics. Problems related to the structure of a shock are considered, where some examples are provided in order to show that quite different behaviors may be found. Asymptotic expansions have been mentioned, which describe completely the behavior of the solution in the neighborhood of a shock. For simplicity, the analysis is restricted to the case of classical gas dynamics.

TL;DR: Several long tryptic peptides obtained from reduced maleylated χ-casein were sequenced: they belonged to the N- and C-terminal moieties of para-χ- casein and could then be joined by chymotryptic overlap peptides.
Abstract: Several long tryptic peptides obtained from reduced maleylated χ-casein were sequenced: they belonged to the N- and C-terminal (37 residues) moieties of para-χ-casein. Several tryptic peptides could then be joined by chymotryptic overlap peptides. 102 amino acid residues of para-χ-casein were thus placed into two long and four shorter sequences. Some structural results were established with a Sequencer which was also employed for a verification of the N-terminal sequence of the χ-caseinoglycopeptide; a previously described short glycopeptide was found again and was reinvestigated.
26 citations
TL;DR: The isolation of Kunitz inhibitor from ovary by affinity chromatography and its characterization by amino acid analysis and partial sequence determination are described.
18 citations
TL;DR: It is suggested that the inhibitory effects of heterosegmental and heterosensory effects on the transmission of cutaneous afferents at the level of the dorsal horn in the spinal cord depends to a large extent on presynaptic mechanisms.
16 citations
TL;DR: The degradation products obtained after the reaction with 3 bird egg-white, human milk and turnip lysozymes under the optimum conditions were separated by gel filtration and quantitatively determined.
15 citations
TL;DR: It is of great interest at the point of view of evolution to compare coelacanth proteins with those of lungfishes and amphibians.
TL;DR: Single crystals of duck egg-white lysozyme II suitable for high-resolution X-ray diffraction studies were obtained at 4, 20 and 37 °C and heavy-atom derivatives have been prepared.
TL;DR: In this article, it was shown that pulse radiolysis of o-m-, and p-xylene mesitylene and pseudocumene give rise to three main absorption spectra at about 600,400 and 320 nm.
