The present paper describes the improvements in MmtDB, a specialised
database designed to collect Metazoa mitochondrial DNA variants. Priority
in the data collection has been given to Metazoa for which a large amount
of variants is available, e.g., for humans. Starting from the sequences
available in the Nucleotide Sequence Databases, the redundant sequences
have been removed and new sequences from other sources have been added.
Value-added information is associated to each variant sequence, e.g.,
analysed region, experimental method, tissue and cell lines, population
data, sex, age, family code and information about the variation events
(nucleotide position, involved gene, restriction site gain or loss).
Cross-references are introduced to the EMBL Data Library, as well as an
internal cross-referencing among MmtDB entries according to tissual,
heteroplasmic, familiar and aplotypical correlation. Furthermore MmtDB has
a new section, AMmtDB: Aligned Metazoan mitochondrial biosequences. MmtDB
can be accessed through the World Wide Web at URL
