All branches are of unit length (one mutational step). Labeled open circles represent observed haplotypes; areas of circles are proportional to the number observed for each haplotype. Filled circles indicate inferred haplotypes not found among sampled individuals. Double lines indicate variable sites (49, 274 and 293) resulting in changes in amino acid. Haplogroups are identified.

Nodal support values are indicated as (posterior probability / maximum parsimony bootstrap / neighbour-joining bootstrap).
An unusual amino acid substitution within hummingbird cytochrome c oxidase alters a key proton-conducting channel
<p>Hummingbirds in flight exhibit the highest metabolic rate of all vertebrates. The bioenergetic requirements associated with sustained hovering flight raise the possibility of unique amino acid substitutions that would enhance aerobic metabolism. Here, we have identified a non-conservative substitution within the mitochondria-encoded cytochrome <i>c</i> oxidase subunit I (COI) that is fixed within hummingbirds, yet exceedingly rare among other vertebrates. This unusual change is also rare among metazoans, but can be identified in several clades with diverse life histories. We performed atomistic molecular dynamics simulations using bovine and hummingbird COI models, thereby bypassing experimental limitations imposed by the inability to modify mtDNA in a site-specific manner. Intriguingly, our findings suggest that COI amino acid position 153 (bovine numbering system) provides control over the hydration and activity of a key proton channel in COX. We discuss potential phenotypic outcomes linked to this intriguing alteration encoded by the hummingbird mitochondrial genome.</p>
