Subject: [ccp4bb] New human genome policy - please read.
H... just saw this. !!!?!??!
I think actually *naming* the proteins would be too extreme. Even the
current alpha-numeric system is overwrought. I liked it better when we
just called proteins p75 or p105. For instance, how many proteins
in the human genome are 75 kD, anyway? My guess is not enough to make
the situation
Why molecular weight? That's just arbitrary.
There is a simple way of referring to proteins which avoids any
ambiguity - by it's sequence. When referring to a protein, we should use
its sequence as an identifier. No ambiguity.

Hi Hongnan
The standard criterion for choosing the optimum weight(s) is to choose the
value(s) that minimise Rfree at convergence of the refinement, i.e. at the
local or global maximum of the likelihood function. Axel Brunger and his group
have published a lot of nice work in this area.
In a powerful counter-proposal I recommend that human genes be named after
actual people. I think many of us have heard of the star catalogue - for
fifty bucks you can have a star named after you (not sure if they still do
this). So, the same deal applies - only a bit more expensive because
The impact factor of UAt4 has recently been upgraded from 'huge' to 'all

Are you talking about chunks of acrylamide? Or perhaps trace molecules?
As for chunks, we normally pass it through a 0.2 um filter before

Hi Vanessa
It is better to get rid of traces of residual acrylamide that may
contaminate your final purified and refolded RNA.
It is usual to have contaminations with monomeric acrylamide. NMR
spectroscopists studying RNA can usually detect its presence on their
spectra.
