Quoting from the text:

When two cysteine amino acids bond to each other, they do so through a disulfide bond.

Ouch. No cys-cys dipeptides? David M

Disulphide bonds in bacteria

I think that the section on disuplhide bonds in bacteria should be made clearer. I am a microbiologist and I'm really unsure to what you are refering when you say as a reversible switch that turns a protein on or off when bacterial cells are exposed to oxidation reactions.

Also bacteria do have the ability to form disulphide bonds but only in the periplasm where it is an oxidizing enviroment.

Formation rates

Is there any info on rates of formation? Or even some references. This is a complicated question, however it may be good to address it rather than ignore it. For instance: rate of thiol to thiol disulfide formation vs rate of CYS to CYS disulfide formation, etc.

Spamming Wikipedia

Biologicalworld.com has spammed wikipedia like no tomorrow. He is a site of only a few pages and a LOT of adsense. Not much information is given except for "protocols" which are not referenced, and cannot be trusted from a site of that quality.
