The quaternary structure and oxygen equilibrium properties of the vascular hemoglobin of the terebellid polychaete, Thelepus crispus Johnson

Characterization of the extracellular haemoglobin of Haemopsis sanguisuga (L.)

“…Here again some annelid haemoglobins appear to possess a Bohr effect, e.g. Thelepus haemoglobin (Garlick & Terwilliger, 1975), whereas others do not, e.g. Neanthes haemoglobin (Economides & Wells, 1975).…”

“…1970; Harrington et al, 1973;Shlom & Vinogradov, 1973;David & Daniel, 1974;Giardina et al, 1975) and from a number of marine worms such as Arenicola (Waxman, 1971), Cirraformia grandis (Swaney & Klotz, 1971), Thelapus crispus (Garlick & Terwilliger, 1975) and Pista pacifica (Terwilliger et al, 1975), comparatively little information seems to be available on the haemoglobins of the freshwater leeches. Svedberg & Pedersen (1940) reported that both Hirudo and Haemopsis haemoglobins had sedimentation coefficients of 57 S-58 S. Needham (1966) briefly reported the absorption spectra of some leech haemoglobins, and Roche et al (1960) reported an electron micrograph of the haemoglobin ofHirudo.…”
