CC -!- FUNCTION: Involved in oxygen transport from gills to the various
CC peripheral tissues. {ECO:0000250|UniProtKB:P02070,
CC ECO:0000269|PubMed:21491556}.
CC -!- SUBUNIT: Heterotetramer of two alpha chains and two beta chains.
CC {ECO:0000303|PubMed:21491556}.
CC -!- TISSUE SPECIFICITY: Red blood cells. {ECO:0000305}.
CC -!- MASS SPECTROMETRY: Mass=16121.5; Mass_error=0.3; Method=MALDI;
CC Evidence={ECO:0000269|PubMed:21491556};
CC -!- MISCELLANEOUS: This fish has just a single hemoglobin. It displays a
CC weak Bohr effect that is not effector-enhanced and shows a propensity
CC to form disulfide-linked polymers in vitro.
CC {ECO:0000269|PubMed:21491556}.
CC -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC ProRule:PRU00238}.
