One-ended subgroups of mapping class groups
Let Σ be a closed orientable surface, and write Map(Σ) for its mapping class group — the group of self-homeomorphisms up to homotopy. The Nielsen-Thurston classification partitions the non-trivial elements of Map(Σ) into finite order, reducible, and pseudoanosov, the last being the “generic” case. A subgroup of Map(Σ) is purely pseudoanosov if every non-trivial element is pseudoanosov. Such a s...
متن کاملThe helix-turn-helix motif of bacterial insertion sequence IS911 transposase is required for DNA binding.
The transposase of IS911, a member of the IS3 family of bacterial insertion sequences, is composed of a catalytic domain located at its C-terminal end and a DNA binding domain located at its N-terminal end. Analysis of the transposases of over 60 members of the IS3 family revealed the presence of a helix-turn-helix (HTH) motif within the N-terminal region. Alignment of these potential secondary...
متن کاملBias between the left and right inverted repeats during IS911 targeted insertion.
IS911 is a bacterial insertion sequence composed of two consecutive overlapping open reading frames (ORFs [orfA and orfB]) encoding the transposase (OrfAB) as well as a regulatory protein (OrfA). These ORFs are bordered by terminal left and right inverted repeats (IRL and IRR, respectively) with several differences in nucleotide sequence. IS911 transposition is asymmetric: each end is cleaved o...
متن کاملEfficient transposition of IS911 circles in vitro.
An in vitro system has been developed which supports efficient integration of transposon circles derived from the bacterial insertion sequence IS911. Using relatively pure preparations of IS911-encoded proteins it has been demonstrated that integration into a suitable target required both the transposase, OrfAB, a fusion protein produced by translational frameshifting between two consecutive op...
متن کاملHyperbolic Surface Subgroups of One-ended Doubles of Free Groups
Gromov asked whether every one-ended word-hyperbolic group contains a hyperbolic surface group. We prove that every one-ended double of a free group contains a hyperbolic surface group if the free group has rank two, or every generator is used the same number of times in the list of amalgamating words. Our method is based on formulating a stronger conjecture on tilings of closed surfaces combin...
