CC   -!- FUNCTION: Involved in oxygen transport from gills to the various
CC       peripheral tissues.
CC   -!- SUBUNIT: Hb 1 is a heterotetramer of two alpha-1 and two beta-1 chains.
CC       {ECO:0000269|PubMed:14511380}.
CC   -!- TISSUE SPECIFICITY: Red blood cells. {ECO:0000305}.
CC   -!- MASS SPECTROMETRY: Mass=16097; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:14511380};
CC   -!- MISCELLANEOUS: This fish has two hemoglobins: Hb1 (major) and Hb2
CC       (about 15-20% of the total). They display the Root effect and the
CC       alkaline Bohr effect, which is enhanced by organophosphate and to a
CC       lesser extent by chloride.
CC   -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00238, ECO:0000305}.
