Correction: Origin and evolution of transporter substrate specificity within the NPF family

Jørgensen ME, Xu D, Crocoll C, Ernst HA, Ramírez D, Motawia MS, Olsen CE, Mirza O, Nour-Eldin HH, Halkier BA. 2017. Origin and evolution of transporter substrate specificity within the NPF family. eLife 6:e19466. doi: 10.7554/eLife.19466.

In our revision, we constructed large multiple sequence alignments and built 3D-homology models to put identified transporter substrate specificities into structural contexts. David Ramirez (DR), Heidi Asschenfeldt Ernst (HAE) and Prof Osman Mirza (OM) performed this work. DR was physically located together with the corresponding authors and he made figures Figure 8, Figure 8–figure supplement 1 and Table 1 in collaboration with and based on data generated by HAE, OM, and DR. HAE and OM are physically located in another campus of UCPH. Due to a collective oversight and despite all authors having revised the manuscript, neither OM nor HAE were included in the author list in the revised and published manuscript. To correct this mistake, Osman Mirza and Heidi Asschenfeldt Ernst have now been added to the author list. All authors have agreed to this change and the article has been corrected accordingly to add to the author list the missing authors whose contributions were critical for the study. The contributions section has also been corrected to specify each author’s contribution to the study.
