beta-lactamase amber mutant

[Michael Benedik]

I am looking for an amber mutant in beta-lactamase either on a plasmid
(with another marker) or on a transposon. If anyone out there in BIONET
land has such a mutant around and would be willing to send it to me
I would be most appreciative. (the amber mutant must be able to be
suppressed by suII (supE) or suIII (supF).   Thanks.
