In rUSP11DU, α-helix 1 has three turns, lacking this insertion.
Neither the control reactions without NADPH, nor assays with microsomes isolated from yeast transformed with pYeDP60 vector lacking an insertion, showed any product formation.
Among the genes lacking an insertion event there was a bias towards short loci that lacked introns and were expressed at very low levels in carpel tissue (Additional file 2).
As the BBM1 domain interrupts the SBHM domain it was inserted after the β-subunit of RNA polymerase first evolved and is thus a derived state compared with genes lacking that insertion.
This observation correlated with the position of the genes relative to the centromere, where gene expression is repressed, since those genes lacking an insertion event were found to be demonstrably closer to the centromeric region (z = -30.76, p < 0.0001).
Our model experiment showed that single DNA molecules carrying a full-length insertion into a 6-kb target can be recovered by Multiplex PCR of target amplicons followed by Hybridization Enrichment (MP-HE), even in the presence of a huge excess of genomic DNA lacking the insertion.
The position of each centromere was taken as: 15,088,987 bp on chromosome 1; 3,608,427 bp on chromosome 2; 13,599,567 bp on chromosome 3; 3,456,519 bp on chromosome 4 and 11,742,755 bp on chromosome 5. Affymetrix gene expression data was analysed as described above, although only 1,913 of the genes lacking an insertion were present on the array.
Class A and C Hsfs contain an extended HR-A/B with 21 and 7 amino acid residues between the HR-A and HR-B region, respectively, whereas class B Hsfs have a compact HR-A/B HR-A/B lacking an inseregion[ 15, 20].
Some others, despite their apparently foreign nature, lack insertion sequences, recombinase genes and specific att sites, and they may contain only fragments of mobility genes.
The 26S probe usually hybridised to several high molecular weight bands indicating the presence multiple IGS families lacking 5S insertions.
