Though I am not so sure, lots of references seem to hint pPS904 was
originally known as pKG5 in this article: Kahana, J., Schnapp,
B.J.,Silver, P.A. (1995) PNAS 92:9707-9711. In its materials section,
the author wrote the following:
Plasmid pKG5 was constructed as follows: wild-type GFP was PCR-
amplified from plasmid TU65 (5) using the 5' Xho I-linked primer
CCGCTCGAGCTATGAGTAAAGGAGAAGA and the 3' 17 primer. The PCR product was
cut with Xho I and Pst I (New England Biolabs).
The NUF2 open reading frame was amplified from plasmid pPS511 (4)
using the BamHI-linked 5' primer GCGGATCCATGAGTAGGAATCAAGATGTC and the
in-frame, XhoI-linked 3' primer
The PCR product was cut with BamHI and Xho I. The two fragments were
ligated together into plasmid pPS293 (a
2-gm URA3 vector with the GALl promoter sequence) cut with BamHI and
So the backbone of pPS904 is just double digested pPS293, whereas the
insert is concatenation of GFP and NUF2.
