WWW-QUERY - AN ONLINE RETRIEVAL-SYSTEM FOR BIOLOGICAL SEQUENCE BANKS

We have developed a World Wide Web (WWW) version of the sequence retri eval system Query: WWW-Query. This server allows to query nucleotide s equence banks in the EMBL/GenBank/DDBJ formats and protein sequence ba nks in the NBRF/PIR format. WWW-Query includes all the features of the on-line sequence browsers already available: possibility to build com plex queries, integration of cross-references with different data bank s, and access to the functional zones of biological interest. It also provides original services not available elsewhere: introduction of th e notion of re-usable sequence lists, integration of dedicated helper applications for visualizing alignments and phylogenetic trees and lin ks with multivariate methods for studying codon usage or for complemen ting phylogenies.
