Subject: DNA sequence from amino acid
To: CCP4BB@jiscmail.ac.uk
Dear all,
I am working on eukaryotic protein and have the amino acid sequence of the
protein but do no know the
reverse translation from protein to nucleotide does not yield a unique
sequence. Your best bet is to use the BLAST feature that searches your protein
sequence against the entire genbank DNA database translated into protein:
Sorry for the off topic. I'm looking for a way to monitor
protein-(potential) ligand interaction. The ligand is small molecule
(mw~250) and we're looking for its potential interaction with couple human
proteins. (We do not know this small molecule interacts with these human
protein or not.)

Ho Jun Lee,
Have you thought about differential scanning fluorimetry (Thermofluor)? With
this biophysical technique you can characterize protein-ligand interactions and
screen a wide variety of ligands using minimal concentration of ligand and
protein. All you need is a quantitative PCR
FRET， CD， Fluorescence， NMR chemical shift assay, isotope-labelled ligand
interaction assay, protein melting temperature assay, gel filtration retention
assay, gyration radius assay by Malls, native page gel analysis, etc.

Specifically for fluorescence
does your ligand fluoresce?
It is possible if it has indol group or some aromatic organic compound
Does your protein has a tryptophan or tyrosines in the binding site?
If yes may be a fluorescence titration experiment could be the solution.

Announcement: Standardization of Amino Acid Nomenclature
The wwPDB is transitioning to use the nomenclature for pyrrolysine and
selenocysteine as recommended by the joint nomenclature committee of
IUPAC/IUBMB.
Starting in January, PYL (for pyrrolysine) and SEC (for selenocysteine) will be

We crystallized a protein at 4 and 22 deg C in different conditions:
from ammonium sulfate in acetate buffer pH 5
and
PEG4000 in Hepes buffer at pH 7.5
In both cases the drops have a slimy skin (almost feels like DNA). We
therefore think that the skin is generated from the protein.
I am sure
Usually the skin is precipitated protein when it comes into contact with air.
In this case, avoiding contact with air may be the only way to avoid the skin,
i.e. crystallise using a technique that is not vapour diffusion, but for
instance microbatch, microdialysis or free interface diffusion.
Do you use any Dnase while purifying your protein?
if not try that and set up new drops to check again.
