Positive selected sites identified in NADH dehydrogenase (Complex I) of S. longiceps. Grey structures represent nuclear-encoded subunits. (a) OXPHOS Complex I with mitochondrial-encoded subunits are represented in different colors: ND2 in yellow, ND4L in blue, ND1 in orange, ND3 in magenta, ND4 in cyan, ND5 in green, ND6 in red. Individual core subunits (b) ND5, (c) ND4, (d) ND2 and (e) ND1 with amino acid site number on positively selected sites. The protein structures were generated using Geneious R788.
