title: Hemoglobin in Frankia, a nitrogen-fixing actinomycete.
abstract: Frankia strain CcI3 grown in culture produced a hemoglobin which had optical absorption bands typical of a hemoglobin and a molecular mass of 14.1 kDa. Its equilibrium oxygen binding constant was 274 nM, the oxygen dissociation rate constant was 56 s(-1), and the oxygen association rate constant was 206 microM(-1) s(-1).
