The beta-barrel Outer Membrane protein Predictor (BOMP) takes one or more fasta-formatted polypeptide sequences from Gram-negative bacteria as input and predicts whether or not they are beta-barrel integral outer membrane proteins.
OMPdb is a database of integral beta-barrel outer membrane proteins from Gram-negative bacteria, classified in functional families. OMPdb entries contain cross-references to other databases, references to the literature and annotation for sequence features (TM segments and signal peptides). The user can submit text searches and run BLAST queries against protein sequences or domain searches against the collection of profile HMMs that represent each family's domain organization.
PRED-TMBB is a tool that takes a Gram-negative bacteria protein sequence as input and predicts the transmembrane strands and the probability of it being an outer membrane beta-barrel protein. The user has a choice of three different decoding methods.
PROFtmb predicts transmembrane beta-barrel (TMB) proteins in Gram-negative bacteria. In addition to running your own predictions, you can also download predictions for all proteins in 78 Gram-Negative bacterial genomes.
PSORT.org provides links to the PSORT family of web-based programs for subcellular localization prediction, including PSORTb and WoLF PSORT, well as other datasets and resources relevant to localization prediction.
