RT   from the Artemia covalent polymer globin.";

CC   -!- SUBUNIT: Artemia hemoglobin is a dimer of two similar sized subunits.
CC       Each subunit represents a globin chain which exists in two forms (alpha
CC       and beta), thus making possible three different phenotypes (HB1,
CC       alpha(2), HB2, alpha/beta, HB3, beta(2)). The globin chain is a polymer
CC       of eight heme-binding covalently linked domains.
CC   -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00238}.
