TMBETA-NET: discrimination and prediction of membrane spanning β-strands in outer membrane proteins

We have developed a web-server, TMBETA-NET for discriminating outer membrane proteins and predicting their membrane spanning beta-strand segments. The amino acid compositions of globular and outer membrane proteins have been systematically analyzed and a statistical method has been proposed for discriminating outer membrane proteins. The prediction of membrane spanning segments is mainly based ...

Discrimination of outer membrane proteins using support vector machines

MOTIVATION Discriminating outer membrane proteins from other folding types of globular and membrane proteins is an important task both for dissecting outer membrane proteins (OMPs) from genomic sequences and for the successful prediction of their secondary and tertiary structures. RESULTS We have developed a method based on support vector machines using amino acid composition and residue pair...

HHomp—prediction and classification of outer membrane proteins

Outer membrane proteins (OMPs) are the transmembrane proteins found in the outer membranes of Gram-negative bacteria, mitochondria and plastids. Most prediction methods have focused on analogous features, such as alternating hydrophobicity patterns. Here, we start from the observation that almost all beta-barrel OMPs are related by common ancestry. We identify proteins as OMPs by detecting thei...

ISOLATION AND PURIFICATION OF MAJOR OUTER MEMBRANE PROTEINS FROM BRUCELLA ABORTUS S-99

Isolation and purification of major outer membrane proteins (OMP) from the cell wall envelope of Brucella abortus S-99 were achieved by sonication, solubilization and membrane fractionation in the presence of non-ionic detergent (Tx-100) and lysozyme treatments, followed by ultracentrifugation. The crude OMP was treated with trypsin to free the preparation from any other protein contaminan...
