Cameron, D. E. & Collins, J. J. Tunable protein degradation in bacteria. Nat. Biotechnol. 32, 1276–1281 (2014).

In this publication, Camaren and colleagues characterize degradation tags with different strengths, substrate to the M. florum Protease mf-Lon. This protease is functional in E. coli and orthogonal to the E. coli ClpXP protease. Percent reductions to the regulated gene were calculated for each tag, but for reasons of consistency with other protease tags, the values are not displayed in the tables. This data can still be accessed in each part's individual page.
