Schematic reprsentation and phylogenetic analysis of P. oxalicum HepA protein. a Schematic representation of HepA. HepA protein consists of chromodomain (CHD) at the N-terminus and chromoshadow domain (CSD) at the C-terminus separated by the hinge region. The different functional roles of the different domains are indicated. b Phylogenetic analysis of HepA/HP1. The tree was constructed using neighbor joining in MEGA 5.0 with 500 bootstrap replicates (coefficients are indicated below the respective nodes). Gaps in the alignment were not considered
