چکیده

Oxygen binding by trout Hb IV has been investigated as a function of pH up to 10 atmospheres (1 MPa) of pure O2. The results bring out an extreme proton-oxygen linkage, which gives rise to a Root effect. They are discussed in relation to the function of the hemoglobin as an oxygen pump. The system is of special interest as providing a prototype of a macromolecule acting as a transducer by coupling two allosterically linked reactions.

Kinetic properties and electron paramagnetic resonance spectra of the nitric oxide derivative of hemoglobin components of trout (Salmo irideus).

The binding of nitric oxide to hemoglobin components of trout (Salmo irideus), i.e., Hb trout I and Hb trout IV, has been studied by optical and electron paramagnetic resonance spectroscopy. Kinetic studies show that the Root effect in Hb trout IV is operative also for NO, since a large increase in the dissociation velocity constant (j(4)) is observed as the pH is decreased below 7. Moreover, t...

Trout hemoglobin: oxygen binding at sub-zero temperatures.

The functional properties of Hb Trout IV, one of the hemoglobin components from trout blood, strongly imply its involvement in the function of the swim-bladder. Thus, Hb Trout IV displays the Root effect, a property common to hemoglobins from teleost fishes, whose characteristic features may be represented by a large pH dependence of the O2 binding properties, both the O2 affinity and the appar...

Blood parameters of Caspian brown trout (Salmo trutta caspius) fingerlings affected by dietary L-ascorbyl-2-polyphosphate

This study was aimed to evaluate the effect of L-ascorbyl-2-polyphosphate as a dietary ascorbic acid source on blood parameters of Caspian brown trout (Salmo trutta caspius), including red blood cell (RBC) count, white blood cell (WBC) and WBC differential. A total number of 600 Caspian brown trout (9.6±0.6 g) fingerlings were randomly distributed in triplicates among five treatments each conta...

Multiple Hemoglobin Components in Cutthroat and Rainbow Trout Multiple hemoglobin components in fish is a well-documented phenomenon, with cutthroat trout having twelve (Figure 1a) and rainbow trout having nine (Figure 1b) hemoglobin components (Braman et al.1977). A high-resolution starch gel electrophoresis method was developed to resolve eight negatively charged hemoglobin components from bo...
