Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
rsiWanti-sigma(W) factor; The anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-W (SigW). Holds SigW, its cognate ECF sigma factor, in an inactive form until released by regulated intramembrane proteolysis (RIP). SigW and RsiW mediate cell response to cell wall stress. RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, PrsW) , then within the membrane itself (site-2 protease, S2P [...] (208 aa)
ctpBSwarming motility protein; Involved in the signal transduction pathway leading to the proteolytic activation of the mother cell transcription factor pro- sigma-K during sporulation. The signaling serine protease CtpB triggers pro-sigma-K processing by cleaving the pre-processed regulatory protein SpoIVFA and is necessary for the proper timing of sigma-K activation. Belongs to the peptidase S41A family. (480 aa)
spoIVFARegulator of SpoIVFB (stage IV sporulation); Implicated in the coupling of mother cell to forespore gene expression. Required for spore formation at 37 degrees Celsius, but not at 30 degrees Celsius. SpoIVFA plays a central role in both maintaining the SpoIVFA/BofA/SpoIVFB complex and anchoring it to the outer forespore membrane. SpoIVFA brings BofA into close proximity to SpoIVFB, allowing BofA to inhibit SpoIVFB. Increased accumulation of SpoIVFA seems to inhibit the activity of SpoIVFB and thus regulates the activation of sigma-K. (264 aa)
spoIVFBMembrane metalloprotease; Implicated in the coupling of mother cell to forespore gene expression. Required for spore formation. Processes the pro-sigma K factor. (288 aa)
oatAPeptidoglycan O-acetyltransferase; Evidence 1a: Function experimentally demonstrated in the studied strain; enzyme. (634 aa)
spoIVBRegulatory membrane-associated serine protease; Plays a central role in the sigma-K checkpoint which coordinates gene expression during the later stages of spore formation. The protease is activated by trans cleavage of the zymogen precursor producing SpoIVB-45 kDa. This undergoes further trimming by cis cleavage to form SpoIVB-43 kDa and SpoIVB-42 kDa. The protease then cleaves the C-terminus of the SpoIVFA metalloprotease activating the latter. (426 aa)
prsWProtease required for RsiW anti-sigma(W) degradation; Involved in the degradation of anti-sigma-W factor RsiW. Responsible for Site-1 cleavage of the RsiW anti-sigma factor. This results, after two other proteolytic steps catalyzed by the RasP and ClpXP proteases, in the release of SigW and the transcription activation of the genes under the control of the sigma-W factor. Seems to be responsible for sensing antimicrobial peptides that damage the cell membrane and other agents that cause cell envelope stress. Therefore it is a protease governing regulated intramembrane proteolysis and r [...] (218 aa)
rsePRegulator of sigma-W protease RasP; Is responsible for site-2 cleavage of the RsiW anti-sigma factor. This results, after a third proteolytic step catalyzed by the ClpXP protease, in the release of SigW and the transcription activation of the genes under the control of the sigma-W factor. Can also cleave liberated signal peptides of PenP and Mpr, probably within in the cell membrane. (422 aa)
sipTType I signal peptidase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the peptidase S26 family. (193 aa)
rsgIsigmaI modulating factor; Anti-sigma factor for SigI. Negatively regulates SigI activity through direct interaction. (381 aa)
bofAInhibitor of the pro-sigma(K) processing machinery; Involved in the mediation of the intercompartmental coupling of pro-sigma K processing to events in the forespore. Inhibits SpoIVFB- processing activity until a signal has been received from the forespore. Could inhibit SpoIVFB metalloprotease activity by coordinating a zinc in the SpoIVFB active site, preventing access of a water molecule and the sequence of pro-sigma K, which are necessary for peptide bond hydrolysis to produce sigma-K. (87 aa)
