15 صفحه اولPromoter scanning for transcription inhibition with DNA-binding polyamides.
When targeted to sequences adjacent to a TATA element, pyrrole-imidazole (Py-Im) polyamides inhibit the DNA binding activity of TATA box binding protein (TBP) and basal transcription by RNA polymerase II. In the present study, we scanned the human immunodeficiency virus type 1 promoter for polyamide inhibition of TBP binding and transcription using a series of DNA constructs in which a polyamid...
متن کاملThe theoretical limits of DNA sequence discrimination by linked polyamides.
Linked polyamides bind in the minor groove of double-stranded DNA in a partially sequence-specific manner. This report analyzes the theoretical limits of DNA sequence discrimination by linked polyamides composed of two to four different types of heterocyclic rings, determining (i) the optimal choice of base-binding specificity for each ring and (ii) the optimal design for a polyamide composed o...
متن کاملX-ray crystal structures of half the human papilloma virus E2 binding site: d(GACCGCGGTC).
The X-ray crystal structure of the DNA decamer d(GACCGCGGTC), containing half the human papilloma virus E2 binding site, has been solved from two crystals grown at different ionic conditions (50 mM MgCl2and 50 mM spermine or 1.56 mM MgCl2and 1.56 mM spermine). Despite the variation in salt concentration, the two DNA structures are in a very similar, A-type DNA conformation, with helical axes cu...
متن کاملFormation of hepatitis B virus covalently closed circular DNA: removal of genome-linked protein.
Hepatitis B virus (HBV) contains a small, partially double-stranded, relaxed circular (RC) DNA genome. RC DNA needs to be converted to covalently closed circular (CCC) DNA, which serves as the template for all viral RNA transcription. As a first step toward understanding how CCC DNA is formed, we analyzed the viral and host factors that may be involved in CCC DNA formation, using transient and ...
