You have explain the lac-operon very good and it has made me look into
more subtile area of proteins. I use to ask you to tell me about
purification of proteins, but know since i have a better view of
proteins, i have a more complex question. Here's the question. Please
comment about what researher's research about when they are studying
certain area of a protein such as Cytochrome C. What i am trying to
say is, if i wanted to publish some reseach on some area in a area in
a protien, what are some area i would do resrach on. I hope you can
see what i am trying to say. I am looking for some area that i can
look at. Something different then protein purification. I am sure
there is a lot area to look at, please suggest sme to consider.

Request for Question Clarification by welte-ga on 15 Jun 2005 18:51 PDT

Are there any topics you've been interested in (for example proteins
that may have clinical medical importance or specific diseases,
protein properties in general such as folding, etc.)?  Protein
research is a vast topic and a good answer to your question will
likely require narrowing down the topic somewhat.

Lets see...

The most interesting part of a protein from a structure - function
relationship are any and all functional domains.  These are "regions"
of the protein which confer some sort of function...ie: DNA binding,
ligand binding sites, enzymatic regions etc.  Try a blast search of
the protein of interest, and take a look at the characterized domains.
 Also, membrane spanning/binding regions are of great interest as this
can effect the localization of the protein.

Basically the entire package is interesting - it depends on what
exactly you want to study.
If you are interested in enzymatics, structural biochemistry, etc...
