Erratum to: Early evolution of the biotin-dependent carboxylase family

Correction

After publication of our work [1], we noticed several major mistakes in the figure images provided for final publication:although the main text and the legends are correct, Figure three (Figure 1)has been replaced by an image present in the Addition file 1 and Figure four (Figure 2), Figure five (Figure 3) and Figure six (Figure 4) are displaced with regard to their correct numbers and legends. Please, accept ourapologies and refer to the correct corresponding Figure three (Figure 1),Figure four (Figure 2), Figure five (Figure 3) andFigure six (Figure 4) that we provide in this erratum. Legends are the same asin the original article.

Figure 1

Maximum likelihood tree of the biotin carboxylase (BC) domain. This tree is based on 284representative sequences and 384 conserved sites and was arbitrarily roosted on the bacterialACC-related sequences. Numbers at nodes indicate bootstrap values higher than 50. Trianglescorrespond to collapsed groups of eukaryotes and Proteobacteria. Colors on leaves represent theaffiliation of the sequences to their respective domain of life: archaea (red), bacteria (blue) andeukaryotes (green). Bars on the right report the functional assignment of the sequences; sequencesthat are not in front of any bar are assumed to bear an acyl-CoA carboxylase activity.

Figure 2

Maximum likelihood tree of archaeal and bacterial biotin carboxylase (BC) domainsequences. This tree is based on 196 representative sequences and 322 conserved sites and wasarbitrarily rooted on the PYC-related sequences. Numbers at nodes indicate bootstrap robustnessvalues higher than 50. Colors on leaves represent the affiliation of the sequences to theirrespective domain of life: archaea (red), bacteria (blue) and eukaryotes (green). Bars on the rightreport the functional assignment of the sequences; sequences that are not in front of any bar areassumed to bear an acyl-CoA carboxylase activity.

Figure 3

Maximum likelihood tree of CoA-substrate related carboxyl tranferase (CCT) domainsequences. This tree is based on 179 representative sequences and 438 conserved sites and wasmidpoint rooted. Numbers at nodes indicate bootstrap robustness values higher than 50. Trianglescorrespond to collapsed groups of eukaryotes. Colors on leaves represent the affiliation of thesequences to their respective domain of life: archaea (red), bacteria (blue) and eukaryotes (green).Bars on the right report the functional assignment of the sequences; sequences that are not in frontof any bar are assumed to bear an acyl-CoA carboxylase activity.

Figure 4

Maximum likelihood tree of pyruvate carboxylase carboxyl tranferase (PCT) domainsequences. This tree is based on 126 representative sequences and 432 conserved sites and wasmidpoint rooted. Numbers at nodes indicate bootstrap robustness values higher than 50. Colors onleaves represent the affiliation of the sequences to their respective domain of life: archaea (red),bacteria (blue) and eukaryotes (green). Bars on the right report the functional assignment of thesequences; sequences that are not in front of any bar have unknown function.
