Growth protocol |
Logarithmic yeast cells were grown in YPR medium and arrested with alpha-factor together with addition of 2% galactose to induce site-specific recombination of native replication origin chromatin domains. Cells were harvested and frozed for subsequent affinity purification.

Extracted molecule |
genomic DNA |
Extraction protocol |
Cell pellets were lysed with dry ice in a commercial coffee grinder and chromatin domains affinity-purified as described in the manuscript. The purified chromatin circles were then treated with the M.CviPI/M.SssI (GpC/CpG-5-methyl-Cytosine-specific) and EcoGII (methyl-6-Adenine-specific) DNA methyltransferases. Methylated DNA was then isolated using Phenol-chloroform extraction.

Data processing |
Base- and modified basecalling were performed with megalodon (v2.3.3) and guppy (v5.0.11) using the res_dna_r941_min_modbases-all-context_v001 model and default parameters. ARS sequences derived from genome build/assembly Saccharomyces_cerevisisae.R64-1-1 targeted for affinity purification, an in vitro assembled nucleosomal array of 12x601 sequences and a spike-in naked plasmid DNA added in the experiments served as spike-in controls to normalize for methylation efficiencies. Assembly: Saccharomyces_cerevisiae.R64-1-1 Supplementary files format and content: comma separated files that contain binary information about methylation
