Depositor Comments

Barnase production plasmid. The vector is the same as that of pMT416. Provides higher yields of barnase than pMT413 or pMT416. This is pTN441 [Okorokov, A.L., Hartley, R.W. and Panov, A,L, Protein Express. and Purif.
5, 547-552 (1994)
] with two HindIII sites in the CI157 gene removed by silent mutations. 900-86: The temperature sensitive repressor gene(CI157) from lambda phage, followed(3')
by its own promoter and, in the forward direction, the PR promoter for barnase. Two silent mutations in this
gene have removed HindIII sites.
901-1872:barnase & barstar genes as in pMT413 & pMT416 from BamH1 site to HindIII site. The copy number is also controlled by the lambda repressor, so that both copy number and barnase production are minimal at 30^o and high at 37^o.
