Detailed Description

Representation of a digestion enzyme for RNA (RNase)

The cutting sites of these enzymes are defined using two different mechanisms: First, a single regular expression that is applied to strings of unmodified RNA sequence and defines cutting sites via zero-length matches (using lookahead/lookbehind assertions). This is the same mechanism that is used for proteases (

See also

ProteaseDigestion). However, due to the complex notation involved, this approach is not practical for modification-aware digestion. Thus, the second mechanism uses two regular expressions ("cuts after"/"cuts before"), which are applied to the short codes (e.g. "m6A") of sequential ribonucleotides. If both expressions match, then there is a cutting site between the two ribonucleotides.

There is support for terminal (5'/3') modifications that may be generated on fragments as a result of RNase cleavage. A typical example is 3'-phosphate, resulting from cleavage of the phosphate backbone.
