had DNA 2.0 codon-optimize S. pombe gene SPCC126.04c [[4]] including biobrick ends for expression of ORF in S. cerevisiae This subunit is homolog of S. cerevisiae SGF73 [[5]] subunit of SAGA and deletion of this subunit in S. cerevisiae results in viable cells but no induction of PAU genes under hypoxic conditions.

Message to DNA 2.0:
The gene is an S. pombe gene called SPBC1921.07c. The protein sequence is:

What I'd like to try is to codon optimize this protein for expression in S. cerevisiae (nuclear expression, not mitochondrial as before!). Again this ORF can have none of the "forbidden" sites (EcoRI, XbaI, NotI, SpeI or PstI ) that are used for cloning. Once it's been optimized the cloning sites can be added by tagging the 5' end before the ATG with: GTTTCTTCGAATTCGCGGCCGCTTCTAGAG and tagging the 3' end after the stop with: TACTAGTAGCGGCCGCTGCAGGAAGAAAC.

Yeast Strains

MH176=hypoxic gene expression reporter strain

from Mark Hickman in Fred's lab:
MATa ura3D0 his3D200 leu2D0 lys2-128d HAP1 DAN3-HIS3
geneology note: = yMH36 DAN3-HIS3 #5 (targeted PAU6, went into DAN3) 05/25/05

related email note 07.12.06 from Mark
Natalie,
I only have PAU5-URA3 or DAN3-HIS3. The DAN3 reporter is tighter on plates, perhaps because the His phenotype is tighter in general. I have not checked whether SGF73 is required for PAU5-URA3 or DAN3-HIS3 induction specifically. But I do know that in an sgf73 delta mutant, there is no hypoxic PAU expression. So I infer that PAU5 and DAN3 expression is affected. We can talk in the afternoon.

NY350 and NY351

MATa ura3D0 his3D200 leu2D0 lys2-128d HAP1 DAN3-HIS3 sgf73::URA3

• geneology: transformed MH176 to Ura+ with product of PCR with KO primers NO99 and NO100

Phenotype MH176 (~wt) v FY2475 (sgf73::KanMX) v FY2474 (sgf29::KanMX)

First spot where individual colonies seen is listed
Better wt control would be FY3 since FY strains are all hap1

Phenotype wt vs sgf73 vs sgf29 vs double

First spot where individual colonies seen is listed
FY3, FY2475, FY2474 and NY356 all FY bkgd so hap1
MH176, NY350 in HAP1 bkgd and carry dan3::HIS3 reporter

Plate type	Temp		FY3 (~wt)	MH176 (~wt)	FY2475 (sgf73::KanMX)	NY350 (sgf73::URA3 in MH176)	FY2474 (sgf29::KanMX)	FY356 (sgf29::URA3 sgf73::KanMX)	comments
YPD	30° 4d		5-6	5-6	5-6	5-6	5-6	5-6	double mutant grows more slowly but same spot # comes up
YPD +1M NaCl	30° 4d		5	5	5-6	5-6	5-6	5-6	no NaCl p-type at 37° or 14° either
YPD +3% formamide	30° 4d		5-6	5-6	3-4	3-4	5-6	1	sgf73 alone has some sensitivity to formamide and sgf29, sgf73 has much greater sensitivity (sgf29 alone has ~no sensitivity). Can use this synthetic phenotype as well as 73 phenotype to look for complementation by pombe subunit (underway 08.02.06). Note: 37° and formamide suppresses the sgf73 phenotype but synthetic phenotype of double still evident. 14° and formamide had showed sensitivity for sgf73::KanMX but not sgf73::URA3...need to recheck this since v. strange.
YPEG	30° 4d		4-5	4-5	2-3	2-3	4-5	v little growth even on 1	effect mimics what is seen on YPD +3%formamide. Can use this for complementation tests as well. Not known why NFCS ~lethal to sgf73, sgf29 double mutant.
YPgal	30° 3d		5-6	5-6	4-5	4-5	5-6	3-4	result recapitulates what was seen before but effects not as dramatic as on YPD +3% formamide or YPEG
