However, they do not share the position 60 amino acid deletion characteristic of subunit 1Dx2.
All nine isolates from the SCG 2 had the RD105 deletion characteristic of the East-Asian clade.
The R220 strains lack the RD150 deletion characteristic of sublineage 7 [ 33, 41], having Rv1671-Rv1674 intand and placing them in sublineage 6.
In contrast, the 4 bp 5′ deletion characteristic of D2 alleles appears to be functionally impaired in reporter gene transfection studies.
Target position 2 included a region of the gag leader sequence containing a 24 bp deletion characteristic of XMRV and PreXMRV-2.
To determine whether Hosim1 and, in particular, the Hosim1-SR form are still active, we performed PCR on cDNA with a primer pair straddling the deletion characteristic of the Hosim1-SR form [ Figure 5, a)].
Furthermore, following phylogenetic analysis of the complete S region, two isolates, which lacked the 33 nucleotide deletion, characteristic of genotype D, were genotype D/E recombinants [ 8, 33, 40].
Interestingly, two temperate bacteriophages of S. mitis, ϕB6 and ϕHER, also code for LytA Spn-like endolysins with 318 amino acid residues (Romero et al. 2004), whereas the EJ-1 inducible prophage isolated from S. mitis strain 101 harbors a gene (ejl) with the 6-bp deletion characteristic of lytASMG alleles (Díaz et al. 1992a).
These deletions characteristic of lymphoid BC were also identified in the 2 samples with mixed immunophenotype.
However, At1g05850 lacks the catalytic-domain deletions characteristic of the class IV and VII proteins.
