I am trying to collect strains of bacteria which belong to
the Enterobacteraceae (for those molecular biologists out there,
E. coli has a lot of relations) for an engineering/evolutionary study.
We plan to screen them for induced beta-galactosidase activity and
catabolite repression, which should tell us whether they have the
lac repressor/CAP protein system.
Those organisms which turn out to have a lac repressor will be
used in PCR reactions to attempt to recover the actual sequences of
the repressor.
Since the presence of the repressor/CAP system may be useful
to those trying to untangle the taxonomy of the Enterobacteraceae, we
are offering to test any strains you send us for these phenotypes. Since
we are molecular biologists, we don't have the expertise to interpret
our results in terms of taxonomy/plylogeny, but possibly others will
be able to use the data, and collaborations are welcome.
What follows is a list of the type of organisms we are searching for.
We will take them from any source--lab stocks, clinical isolates, old
lyophylized cultures, etc. We already have ATCC strains for some of
these organisms, but have found that "identical" organisms can give
widely differing results in the PCR reaction.
If interested, contact us at the following address:

We also have a parallel project to PCR out sequences for Thymidylate
synthase from major divisions of eubacteria and archebacteria. If you
are working with some of these organisms and are interested in getting
these sequences, contact us.
