CC -!- FUNCTION: Involved in oxygen transport from gills to the various
CC peripheral tissues. {ECO:0000305}.
CC -!- SUBUNIT: Heterotetramer of two alpha chains and two beta chains.
CC {ECO:0000269|PubMed:5076774}.
CC -!- TISSUE SPECIFICITY: Red blood cells. {ECO:0000305}.
CC -!- MISCELLANEOUS: This fish has ten hemoglobins, 8 of which are anodal and
CC 2 cathodal. The cathodal tetramers do not exhibit the Bohr effect, due
CC to lack of the C-terminal His in the beta chains and to blocking of the
CC alpha-amino group on the N-terminal residue of the alpha chains. The
CC possession of both anodal and cathodal hemoglobins may be a
CC physiological advantage for fish living in fast-moving water habitats.
CC {ECO:0000269|PubMed:5076774}.
CC -!- MISCELLANEOUS: This fish possesses 6 types of hemoglobin chains,
CC including a major alpha chain, a minor alpha chain, two major beta
CC chains, and two minor beta chains. {ECO:0000269|PubMed:5076774}.
CC -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC ProRule:PRU00238}.
