Plasmid: pATH1

Source/Vendor: ATCC
Analyze: Sequence
Plasmid Type: Unspecified
Cloning Method: Unknown
Size: 3779
Notes:
The PvuII-HindIII fragment from the 5' end of the trp operon through nt 1999 of ECOTGP, which is in trpD CDS, was ligated to the HindIII-PvuII fragment of pBR322 containing the bla gene for Amp-resistance and origin of replication, but not the rop gene, which encodes a negative regulator of ColE1 replication. In addition, the EcoRI site in the pBR322 backbone was eliminated to make plasmid pKRS101. The BglII-HindIII fragment (nt 1392 of trpE to the end of the trpD sequence present in pKRS101) was replaced with a BamHI-EcoRI fragment and an EcoRI-HindIII fragment, both from the MCS of M13mp12 to make plasmid pATH1 (see GenBank M32985). The nucleotides remaining in the codon after cutting the vector with the given enzyme are (S-not for 5'-juncture because of stop codon in frame): BamHI-2, ClaI-3S, EcoRI-2, HindIII-2S, SalI-2S, XbaI-2S. Restriction digests of the clone give the following sizes (kb): BamHI--3.8; EcoRI--3.8; HindIII--3.8. (ATCC staff) Nucleotide 1 is the first in the trp fragment, at the beginning of a PvuII site 261 nucleotides upstream of the transcription start site. The multiple cloning site follows codon 323 of trpE. pATH1 was constructed from the following: 1-1391, the trp promoter and most of trpE; 1392-1455, multiple cloning sequence; 1456-3779, ClaI/PvuII fragment of pBR322, including bla (1696-2556) and ori. The EcoRI site was altered. Fusion proteins are produced in Escherichia coli usually in an insoluble form which facilitates purification. Hybrid proteins larger than 90 kDa are not expressed as efficiently as shorter ones. To prevent recircularization of the vector, the depositors recommend including 30 - 50 U of calf alkaline phosphatase in the restriction enzyme digestion used to prepare the vector. Escherichia coli containing pATH vectors should be grown on medium supplemented with tryptophan to prevent expression. Storage as DNA at -20C is preferred; long term storage as cells may result in selection of non-expressing promoter mutations. [1] This is one of a series of vectors (ATCC 37695-37703) designed to facilitate expression of an open reading frame as a trpE fusion protein. Medium is -1 1065 plus ampicillin (50 ug/ml) & tryptophan (10 ug/ml). Hosts: E.coli RR1, E.coli. Related vectors: pKRS101, pBR322, M13mp12.
