Hi Tim,

Lactococcus lactis can also produce SeMet proteins, see:
Berntsson et al. Selenomethionine incorporation in proteins expressed in Lactococcus lactis. Protein Sci (2009) vol. 18 (5) pp. 1121-7

Cheers,
Ronnie

Dear all,

I already received a couple of replies.

* mammalian cells:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2242577/pdf/2008.pdf
mentions several mammalian cell lines, including CHO, HEK239, and COS.
Apparently, Lec8 have been used, too.
* Yeast
* stable S2 insect cells
* baculovirus expression system
* in addition to E.coli, P. aeruginosa was also mentioned.

Thanks to everyone who replied.

Tim

Dear all,

since I am currenty preparing a lecture on crystallography I am wondering about
the status quo of the production of SeMet proteins.
In 2003, if I remember correctly, it was possible to express SeMet proteins in
E.coli and insect cells.

Has this been extended to other systems, and if so, which ones?

Thanks a lot,
Tim
