What is the ' sigma' in sigma factor? Why the different numbers? (i.e. what is the naming convention based on?) It does not appear to be based on molecular weight as with the heat shock proteins (because sigma 70 is about 40 k Da, at least in the PDB). Is it a parameter based on ultracentrifugation? Thanks for any insight. -- Dan| (talk) 16:37, 30 June 2006 (UTC)
Sigma 70 is 70kDA in E.coli
Regarding the proposal to merge with Sigma protein and Sigma subunit by Tameeria:
Merged by redirecting sigma protein and sigma subunit to sigma factor. – Clockwork Soul 16:42, 21 March 2008 (UTC)
The "initiation factor" link at the beginning of this article directs to a description of translation, rather than transcription, initiation factors. —Preceding unsigned comment added by 129.137.226.9 ( talk) 17:50, 22 July 2009 (UTC)
Should Specificity factor be merged into this article? I'll post further queries to appropriate people when I get the time - I just got back from vacation (if someone else wishes to do so, feel free!). Allens ( talk) 02:05, 4 January 2012 (UTC)
