As demonstrated by August Krogh et al. a century ago, the oxygen-binding reaction of vertebrate haemoglobin is cooperative (described by sigmoid O(2) equilibrium curves) and modulated by CO(2) and protons (lowered pH) that - in conjunction with later

The viscosity of blood from rainbow trout was measured following manipulation of haematocrit by bleeding, hypoxia. exercise, and anaesthesia. Blood viscosity when measured at high shear rate (225 s 1) was proportional to haematocrit, but the dependen

The teleost spleen is a discrete organ containing, in addition to erythrocytes sequestered from the circulation, erythropoietic tissue involved in the synthesis of new erythrocytes. In this division into supply and synthesis, there appear to be some

The role of the amino acid at position alpha(38) in haemoglobin has been probed using site-directed mutagenesis. When the Thr residue at position alpha(38) (which is totally conserved in all mammals) is changed to a Gln, the equilibrium properties of

The extent and kinetics of reassembly of the four groups of linkers L1-L4 with 213 kDa subassemblies of twelve globin chains D, (bac)3(d)3, isolated from the approximately 3.6 MDa hexagonal bilayer (HBL) hemoglobin (Hb) of Lumbricus terrestris, was i

Polychaete species belonging to the genus Branchipolynoe are commensal with mussels from deep-sea hydrothermal vents and cold-seeps. Possessing hemoglobins (Hbs), the species B. symmytilida, which is found in the mussel Bathymodiolus thermophilus on

The functional and structural basis for the Root effect has been investigated in the anodic hemoglobin of the European eel, Anguilla anguilla. This hemoglobin exhibits a large Bohr effect, which is accounted for by oxygen-linked binding of seven to e

As in other fish, the cathodic hemoglobin of the eel Anguilla anguilla is considered to play an important role in oxygen transport under hypoxic and acidotic conditions. In the absence of phosphates this hemoglobin shows a reverse Bohr effect and hig

Oxygen transport to vertebrate tissues is dependent upon (a) the intrinsic O2-binding properties of haemoglobin (Hb) and (b) modulation by allosteric effectors, such as nucleoside triphosphates (NTP), that depress Hb O2-affinity in fish red cells. Wh
