Sentence examples for modification systems have from inspiring English sources

At present, several classes of histone modifications and their respective enzymatic modification systems have been identified (Table 1) [ 26].

Putative restriction modification systems have been identified using the Restriction-ModificationFinder-1.0 server (https://cge.cbs.dtu.dk/services/Restriction-ModificationFinder-1.0/) based on the Restriction Enzyme database (REBASE, http://rebase.neb.com/rebase/rebase.html) [ 56].

At present several classes of histone modifications and their respective enzymatic modification systems have been identified [ 72, 75] and amongst their epigenetic substrate marks, lysine and arginine modifications are probably the best studied: acetylation and methylation of lysine residues, as well as methylation of arginine [ 72, 75, 76].
