PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Minor correction to sequence data

Cameron Neylon   (2014-03-25 11:12)  PLOS

In table 1 the generation of two variant β-glucuronidases with increased β-galactosidase activity (labelled as C4.1 and C4.2) is described. Further analysis of the sequencing of these mutants has revealed a minor error in the listed mutation sites. Mutant C4.1 also contains a silent mutation. Mutant C4.2 is missing mutation sites N166T and N412D and the listing of a silent mutation. These make the mutants:

C4.1: G245A/K370R/W529L

C4.2: V67D/N166T/K370R/N412D/W529L

These changes do not affect the overall results and conclusions of our report.
