This is one source paper I found recently, and there are lots of others.

Dear Jacob,
You did not miss the 101 class, it is just too much to remember.

E. coli metabolome when growing on glucose (Lehninger, 2013):
http://www.fullonline.org/science/ecoli_metabolome.png

The book does not provide explanation for this, but I remember reading 
somewhere else that glutamate is a metabolic intermediate that mediates osmotic 
regulation. When growing in high osmotic environments,  E. coli accumulates 
glutamate to match the outside osmotic pressure. Hopefully this is not 
incorrect, because that's what I've been telling my students.
Regards,
       Napo

Assunto: [ccp4bb] Completely Off-Topic
Dear Crystallographers,

Was anyone else aware that in E coli the intracellular glutamate concentration 
is ~100 mM? Also other cell types (yeast, mammalian) are 10s mM. Anything to 
say about this? I learned of this just recently, and have been amazed about it 
for more than a week. Did I miss this in Biochem 101? Does it matter?
