Subcellular localization predictions
(return to top)
Information about bacterial subcellular localization is important for protein function prediction and identification of suitable diagnostic targets. Predictions generated for Las by PSORTdb are shown are provided (Excel)


Proteins with predicted signal peptides
(return to top)
Bacterial proteins mediating interactions with the environment and with host organisms are commonly found in the periplasm and bacterial outer membrane. To identify the likely set of Las-encoded proteins targeted to regions of the cell outside the cytoplasm, all predicted Las proteins were evaluated for the presence of predicted signal peptides using SignalP 3.0. SignalP generates predictions based on a combination of artificial neural networks and hidden Markov models.

Predicted lipoproteins
(return to top)
Bacterial lipoproteins are secreted across the bacterial inner membrane where upon attached lipid anchors the protein in the inner or outer membrane. To identify the likely set of Las-encoded lipoproteins, all predicted Las proteins were evaluated for the characteristic lipoprotein signal peptidase cleavage site using LipoP 1.0 which generates predictions using hidden Markov models.

Predicted RirA binding sites (return to transcription factor list)

Predicted binding sites in the Ca. L. asiaticus genome sequence for the RirA transcriptional repressor. Predictions were made using a hidden Markov model (HMM) and position weight matrix (PWM) derived from experimentally confirmed RirA binding sites in Sinorhizobium meliloti described by Rodionov, 2006 (PMID: 17173478). Errors for each prediction correspond to the likelihood of the motif sequence being found at random in the genome in question (methods manuscript in preparation)
