MBIS--an integrated system for the retrieval and analyses of sequence data from nucleic acids and proteins.

A computer-based system termed MBIS (the Molecular Biological Information Service), written in FORTRAN77 and Digital Command Language (DCL) and running on a Digital Equipment Corporation VAX computer under the VMS operating system (V4.1) is in use at the Division of Molecular Biology. MBIS consists of three main sections: 1) The utility section, used by the system's manager to tailor the five commonly available databases so that they are useable by the applications programmes running on the system; 2) The retrieval section, used to find and extract specific sequences or bibliographic information, and 3) The analytical section, used to analyse and compare sequences either extracted from the databases or input by the user. The nucleotide databases maintained are GenBank, EMBL and PIR (Protein Identification Resource, National Biomedical Research Foundation) and the peptide databases are PIR and NEWAT. In addition, users can originate and maintain their own databases. Those programmes which feature graphics output are compatible with most emulators of the Tektronix 4010 terminal.
