The ACNUC Sequence Retrieval System

ACNUC is a retrieval system for the nucleotide and protein sequence databases GenBank, EMBL, UniProt/SWISS-PROT or NBRF-PIR, and for many other databases following the same formats.

ACNUC allows to select sequences from many criteria from these databases, to translate protein-coding genes in protein, and to extract selected sequences in user files. ACNUC is very efficient in providing direct access to coding regions (e.g. protein coding regions, tRNA or rRNA coding regions) of DNA fragments present in GenBank and in EMBL.
