S. Pongor et al., THE SBASE PROTEIN DOMAIN LIBRARY, RELEASE 3.0 - A COLLECTION OF ANNOTATED PROTEIN-SEQUENCE SEGMENTS, Nucleic acids research, 22(17), 1994, pp. 3610-3615
SBASE 3.0 is the third release of SBASE, a collection of annotated pro
tein domain sequences. SBASE entries represent various structural, fun
ctional, ligand-binding and topogenic segments of proteins as defined
by their publishing authors. SBASE can be used for establishing domain
homologies using different database-search tools such as FASTA [Lipma
n and Pearson (1985) Science, 227, 1436-1441], and BLAST3 [Altschul an
d Lipman (1990) Proc. Natl. Acad. Sci. USA, 87, 5509-5513] which is es
pecially useful in the case of loosely defined domain types for which
efficient consensus patterns can not be established. The present relea
se contains 41,749 entries provided with standardized names and cross-
referenced to the major protein and nucleic acid databanks as well as
to the PROSITE catalogue of protein sequence patterns. The entries are
clustered into 2285 groups using the BLAST algorithm for computing si
milarity measures. SBASE 3.0 is freely available on request to the aut
hors or by anonymous 'ftp' file transfer from [ftp.icgeb.trieste.it].
Individual records can be retrieved with the gopher server at [icgeb.t
rieste.it] and with a www-server at [http://www.icgeb.trieste.it]. Aut
omated searching of SBASE by BLAST can be carried out with the electro
nic mail server [sbase @ icgeb.trieste.it]. Another mail server [domai
n @ hubi.abc.hu] assigns SBASE domain homologies on the basis of SWISS
-PROT searches. A comparison of pertinent search strategies is present
