glutathione S-transferase-chemotaxin C5a-GFP + H2O

?
N-terminal His-tagged C5a fusion protein + H2O
?
-
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry analysis of cleaved HT-C5a indicate a loss of 830 Da, consistent with the removal of seven residues from the C-terminus
-
-
?
chemotaxin C5a
?
-
cleavage site is His-Lys rather than Lys-Asp, native protein is resistant to cleavage, suggesting that His-Lys bond is inaccessible prior to proteolytic cleavage by C5 convertase
-
?
chemotaxin C5a + H2O
?
-
cleaves between His67 and Lys68 or Ala58 and Ser59
-
?
chemotaxin C5a + H2O
?
-
removes a six-amino-acid fragment and thereby inactivates this chemotaxin
-
?
chemotaxin C5a + H2O
?
-
cleavage between histidine-67 and lysine-68 near the C-terminus
-

-
-
alters the normal host inflammatory response by delaying the accumulation of PMNLs at the foci of streptococcal infection

additional information
?
-
-
binds directly to HEp2 and A549 cells, binds to the extracellular matrix protein fibronectin, role in cell invasion
-
?
additional information
?
-
-
mediates adherence to fibronectin, role in immune evasion by attenuating recruitment of polymorphonuclear leukocytes to the site of infection

-
fibronectin adhesin activity. Affinity for fibronectin is very high for both full-length recombinant ScpB and the 110-amino-acid phage display fragment
-
-
?
additional information
?
-
-
group B Streptococci do not bind to fibronectin in solution, but bind to fibronectin adsorbed onto a solid surface through ScpB, that binds to a motif created by the juxtaposition of multiple fibronectin molecules
