Or you could just bug me to find the PNGaseF expression plasmid that I should 
have in the freezer somewhere!

Hi Aaron,

There is a very simple way around (or through :-)) such walls of silence. Both 
enzymes are rather small (see UniProt Q9XBM8 and P36911) and in a week or so 
you can have synthetic cDNAs built as you wish. The cost should be equivalent 
to the purchase of a few enzyme aliquots, so not a bad deal in long term.

Best wishes,

radu

[ccp4bb] Deglycosylation enzymes

2010-06-18 Thread Aaron Oakley
Hi all,

I am looking to obtain plasmids encoding the deglycosylating enzymes 
peptide-N-glycosidase F and endoglycosidase F1
for expression as fusion proteins with GST. They were described in the 
following paper:

Deglycosylation of proteins for crystallization using recombinant fusion 
protein glycosidases.
F. Grueninger-Leitch, A. D'Arcy, B. D'Arcy, and C. Chène
Department of Gene Technologies, Pharma Preclinical Research, F. Hoffmann-La 
Roche AG, Basel, Switzerland.
Protein Sci. 1996 December; 5(12): 2617–2622.

Has anyone here had any luck obtaining them? I understand that a materials 
transfer agreement is needed.
I have tried contacting the authors and Hoffmann-La Roche via four difference 
channels and have met with a
wall of silence! Any help here would be appreciated!

With thanks,
