Hi Massimo
2008/10/13 Massimo Heitor massimohei...@gmail.com:
I am looking at the residue sequence for a protein that I'm studying for a
class and I have a few questions.
I understand the regular amino acid codes (CYS, ARG, LEU, etc...).
What is NAG? I see one sequence NAG NAG NAG NAG (resisting off-topic joke)
If you have access to wikipedia a quick search would indicate that you
might be looking at N-Acetylglucosamine
(http://en.wikipedia.org/wiki/N-Acetylglucosamine).
What is HOH? I see about 107 HOH elements in a row. They are all colored
red. What is that?
Ok, I'm going to ask a question. What molecule has to H atoms and one O?
On the sequence number bar, I see one break represented as //, and one gap
in the numbering. 130-133 is NAG NAG NAG NAG, and 140-246 is all HOH, but
there is seemingly nothing at positions 134-139. Why is that? What is the
difference between a // break and a numbering sequence gap?
I don't use the sequence bar myself so I'll have to pass an that question.
Thanks!
Hope this helps!
