Abstract
Electron microscopy analyses of Iguana iguana blood preparations revealed the presence of mitochondria within erythrocytes with well-structured cristae. Fluorescence microscopy analyses upon incubation with phalloidin-FITC, Hoechst 33342 and mitochondrial transmembrane potential (Δψm)-sensitive probe MitoTracker Red indicated that mitochondria i) widely occur in erythrocytes, ii) are polarized, and iii) seem to be preferentially confined at a "perinuclear" region, as confirmed by electron microscopy. The analysis of NADH-dependent oxygen consumption showed that red blood cells retain the capability to consume oxygen, thereby providing compelling evidence that mitochondria of Iguana erythrocytes are functional and capable to perform oxidative phosphorylation.

Abstract
The alpha- and beta-globin gene families of jawed vertebrates have diversified with respect to both gene function and the developmental timing of gene expression. Phylogenetic reconstructions of globin gene family evolution have provided suggestive evidence that the developmental regulation of hemoglobin synthesis has evolved independently in multiple vertebrate lineages. For example, the embryonic beta-like globin genes of birds and placental mammals are not 1:1 orthologs. Despite the similarity in developmental expression profiles, the genes are independently derived from lineage-specific duplications of a beta-globin pro-ortholog. This suggests the possibility that other vertebrate taxa may also possess distinct repertoires of globin genes that were produced by repeated rounds of lineage-specific gene duplication and divergence. Until recently, investigations into this possibility have been hindered by the dearth of genomic sequence data from nonmammalian vertebrates. Here, we report new insights into globin gene family evolution that were provided by a phylogenetic analysis of vertebrate globins combined with a comparative genomic analysis of three key sauropsid taxa: a squamate reptile (anole lizard, Anolis carolinensis), a passeriform bird (zebra finch, Taeniopygia guttata), and a galliform bird (chicken, Gallus gallus). The main objectives of this study were 1) to characterize evolutionary changes in the size and membership composition of the alpha- and beta-globin gene families of tetrapod vertebrates and 2) to test whether functional diversification of the globin gene clusters occurred independently in different tetrapod lineages. Results of our comparative genomic analysis revealed several intriguing patterns of gene turnover in the globin gene clusters of different taxa. Lineage-specific differences in gene content were especially pronounced in the beta-globin gene family, as phylogenetic reconstructions revealed that amphibians, lepidosaurs (as represented by anole lizard), archosaurs (as represented by zebra finch and chicken), and mammals each possess a distinct independently derived repertoire of beta-like globin genes. In contrast to the ancient functional diversification of the alpha-globin gene cluster in the stem lineage of tetrapods, the physiological division of labor between early- and late-expressed genes in the beta-globin gene cluster appears to have evolved independently in several tetrapod lineages.

Abstract
We determined the complete amino acid sequences of the Erabu sea snake (Laticaudia semifasciata) hemoglobin by analyzing the intact globin chains, enzymatically digested fragments, and chemical cleavage fragments to clarify the molecular evolution and phylogenetic classification of the sea snake. The Erabu sea snake has two types of hemoglobin components, Hb-I and Hb-II, which contain different alpha- and beta-chains. This is the second report of the complete primary structure for hemoglobin of snakes. The sequences were compared with those of other reptilian hemoglobins. Amino acids at positions critical for the structure and physiological functions of hemoglobin were loosely conserved. The requirements for binding of ATP and of diphosphoglycerate as allosteric effectors of beta-globins seemed to be fulfilled.

Abstract
The complete primary structures of alpha D-2- and beta-globin of hemoglobin D (Hb D) from the Aldabra giant tortoise, Geochelone gigantea, have been constructed by amino acid sequencing analysis in assistance with nucleotide sequencing analysis of PCR fragments amplified using degenerate oligonucleotide primers. Using computer-assisted sequence comparisons, the alpha D-2-globin shared a 92.0% sequence identity versus alpha D-globin of Geochelone carbonaria, a 75.2% versus alpha D-globin of Aves (Rhea americana) and a 62.4% versus alpha A-globin of Hb A expressed in adult red blood cells of Geochelone gigantea. Additionally, judging from their primary structures, an identical beta-globin was common to the two hemoglobin components, Hb A and Hb D. The alpha D-2- and beta-globin genes contained the three-exon and two-intron configurations and showed the characteristic of all functional vertebrate hemoglobin genes except an abnormal GC dinucleotide instead of the invariant GT at the 5' end of the second intron sequence. The introns of alpha D-2-globin gene were both small (224-bp/first intron, 227-bp/second intron) such that they were quite similar to those of adult alpha-type globins; the beta-globin gene has one small intron (approximately 130-bp) and one large intron (approximately 1590-bp). A phylogenetic tree constructed on primary structures of 7 alpha D-globins from Reptilia (4 species of turtles, 2 species of squamates, and 1 species of sphenodontids) and two embryonic alpha-like globins from Aves (Gullus gullus) and Mammals (Homo sapiens) showed the following results: (1) alpha D-globins except those of squamates were clustered, in which Sphenodon punctatus was a closer species to birds than turtles; (2) separation of the alpha A- and alpha D-globin genes occurred approximately 250 million years ago after the embryonic alpha-type globin-genes (pi' and zeta) first split off from the ancestor of alpha-type globin gene family.

Abstract
The importance of intraerythrocytic organic phosphates in the allosteric control of oxygen binding to vertebrate hemoglobin (Hb) is well recognized and is correlated with conformational changes of the tetramer. ATP is a major allosteric effector of snake Hb, since the absence of this nucleotide abolishes the Hb cooperativity. This effect may be related to the molecular weight of about 32,000 for this Hb, which is compatible with the dimeric form. ATP induces a pH-dependent tetramerization of deoxyHb that leads to the recovery of cooperativity. This phenomenon may be partially explained by two amino acid replacements in the beta chains (CD2 Glu-43 --> Thr and G3 Glu-101 --> Val), which result in the loss of two negative charges at the alpha1beta2 interface and favors the dissociation into dimers. The ATP-dependent dimer left arrow over right arrow tetramer may be physiologically important among ancient animal groups that have similar mutations and display variations in blood pH that are governed by these animals' metabolic state. The enormous loss of free energy of association that accompanies Hb oxygenation, and which is also observed at a much lower intensity in higher vertebrate Hbs, must be taken into consideration in allosteric models. We propose that the transition from a myoglobin-like protein to an allosteric one may be of evolutionary significance.

Abstract
Cobra snake Naja naja naja hemoglobin shows four bands on Triton electrophoresis. We present the primary structure of one alpha and one beta chain. The separation of polypeptide chains was achieved by ion exchange chromatography on carboxymethyl cellulose column. The amino acid sequence was established by automatic Edman degradation of the native chains and tryptic and hydrolytic peptides in a gas-phase sequencer. The structural data are compared with those of human and other reptile hemoglobins and reveal not only large variations from human but within reptiles. The amino acid exchanges involve several subunit contacts and heme binding sites. This is the first study on the hemoglobin of a land snake. There are only two amino acid sequences of sea snake hemoglobin (Microcephalophis gracilis gracilis and Liophis miliaris) reported in the literature.

Abstract
The hemoglobin of the sea snake Microcephalophis gracilis was purified and the primary structure of the alpha and beta chains determined. This is the first sea snake hemoglobin structure characterized, and apparently also the first complete structure of any snake hemoglobin (an alpha chain of a viper was known), allowing judgments of reptilian variants. Variations between the sea snake form and other reptilian forms are large (52-65 differences for the alpha chains), of similar order as those between the sea snake and avian (56-65 differences) or human (58 differences) forms. Functionally, 19 residues at alpha/beta contact areas and 7 at heme contacts are exchanged in relation to the human alpha and beta chains. Four positions of the sea snake hemoglobin contain residues thus far unique to this form. However, all replacements appear compatible with conserved overall functional properties.

Abstract
The erythrocytes of the adult Cormorant contain two hemoglobin components in a ratio of 83% Hb A to 17% Hb D. The primary structures of the alpha A-, alpha D- and beta-chains are presented. The globin chains were separated by high-performance liquid chromatography and cleaved enzymatically and/or chemically. The native chains and their fragments were sequenced using liquid- or gas-phase sequencers, and the peptides aligned using the homology to human and to avian hemoglobin sequences. Compared to human hemoglobin, there are 46 amino-acid replacements in the alpha A-chains (67.4% homology), 65 replacements in the alpha D-chains (53.9% homology) and 45 replacements in the beta-chains (69.2% homology). In the functionally important regions, the percentage of amino-acid substitutions, as compared to human hemoglobin, is 13.2% in the alpha A-, 19.0% in the alpha D - and 16.0% in the beta-chains. The importance of the replacement beta 135 arginine (other birds)----glycine (Cormorant) in the phosphate-binding pocket and its effect on phosphate binding will be discussed.
