(See quot. 1957.)
1957A. Gottschalk in Biochim. & Biophys. Acta XXIII. 646 We propose the name ‘neuraminidase’ for the enzyme and define its action as the hydrolytic cleavage of the glycosidic bond joining the keto group of neuraminic acid to d-galactose or d-galactosamine and possibly to other sugars. 1960― in P. D. Boyer et al. Enzymes (ed. 2) IV. xxvii. 472 The wide distribution of neuraminidase among microorganisms inhabiting the respiratory and intestinal tracts would suggest that the enzyme has been evolved as a vital mechanism to guard the microbe against solitary confinement in a coating of host mucin. Ibid. 473 Neuraminidase has not been met in animal tissues. It is not a metabolic enzyme but a tool to facilitate accommodation of a parasite or symbiont within its host. 1970New Scientist 8 Jan. 51/1 Influenza viruses possess another surface protein, the enzyme neuraminidase. Ibid. 31 Dec. 608/3 The enzyme neuraminidase, injected into mice as a post-coital contraceptive, seemed to be the most effective base for a ‘morning-after pill’ of any yet tried. |
