Abstract

The effect of the chemical buffering component Tris (hydroxy-methyl-amino-methane) and of chloride ions on the oxygen binding of tarantula hemocyanin was studied at constant pH. It revealed that Tris at micromolar concentrations decreases the oxygen pressure at half-saturation (p50) by a factor of more than two, whereas chloride does not influence oxygen affinity. A thermodynamic analysis in ...
