Regulation of gene expression in restriction-modification system Eco29kI
The Eco29kI restriction-modification (R-M) system consists of two partially overlapping genes, eco29kIR, encoding a restriction endonuclease and eco29kIM, encoding methyltransferase. The two genes are thought to form an operon with the eco29kIR gene preceding the eco29kIM gene. Such an organization is expected to complicate establishment of plasmids containing this R-M system in naive hosts, si...
متن کاملComplex Multiplication
These are preliminary notes 1 for a modern account of the theory of complex multiplication. A shortened (minimal) version will be included in my book on Shimura varieties, and a complete longer version may one day be published separately. Please send comments and corrections to me at [email protected]. 1 This should be taken seriously: there are omissions, repetitions, clumsy statements and proof...
متن کاملComplex Multiplication
Class field theory describes the abelian extensions of a number field using the arithmetic of that field. The Kronecker-Weber theorem states that all abelian extensions of the rationals are contained in cyclotomic fields. As we know, cyclotomic fields can be generated by special values of the exponential function e, and we call this the theory of complex multiplication for Gm. We would thus lik...
متن کاملJacobians with Complex Multiplication
We construct and study two series of curves whose Jacobians admit complex multiplication. The curves arise as quotients of Galois coverings of the projective line with Galois group metacyclic groups Gq,3 of order 3q with q ≡ 1 mod 3 an odd prime, and Gm of order 2 . The complex multiplications arise as quotients of double coset algebras of the Galois groups of these coverings. We work out the C...
متن کاملRestriction and modification in Bacillus subtilis: sequence specificities of restriction/modification systems BsuM, BsuE, and BsuF.
The sequence specificities of three Bacillus subtilis restriction/modification systems were established: (i) BsuM (CTCGAG), an isoschizomer to XhoI; (ii) BsuE (CGCG), an isoschizomer to FnuDII; and (iii) BsuF (CCGG), an isoschizomer to MspI, HpaII. The BsuM modification enzyme methylates the 3' cytosine of the recognition sequence. The BsuF modification enzyme methylates the 5' cytosine of the ...
