sigma factors of e coli - genral table? (Jul/02/2007 )

well my question comes from my incapacity to find the coresponding number for factor sigma S
I know i may do more stuff... but my question is now slight different.
I've switched to the aim of doing a sum up table but some informations are missing... including rpoS.... grrrrr

so may you redirect me to a quite recent review of these factors?

i found a good old review but rpoS is still missing.....
for info : helmann and chamberlain ann rev biochem 1988 Structure and Function of Bacterial Sigma Factors.pdf

This is a table from B. Lewin - Genes VIII
Hope it answers your question.
