Constants

BUILTIN

Built-in catalogue: widely used commercial Type II enzymes, hand-listed from published recognition sequences and cut positions (scientific facts) and verified against Biopython 1.85 Bio.Restriction by scripts/check_enzymes.py. REBASE itself is not redistributed (see docs/restriction.md); it can be installed locally.

Functions

active_catalogue

The active catalogue: an installed one, otherwise the built-in set.

find_sites

Find exact sites and nominal cuts. Does not model methylation, reaction conditions, star activity, accessibility, minimum flanking DNA or digest fragments. Ambiguous input is rejected rather than reported as a misleading negative scan.

install_catalogue

Install the process-wide catalogue (once, before the first scan). Returns false if a catalogue was already active.
