Abstract
The Pseudomonas syringae pv. syringae 61 hrpJ and hrpI genes were sequenced and found to encode predicted proteins of 37,710 Da and 76,490 Da, respectively. The products of these genes were confirmed by T7 polymerase-dependent expression and sodium dodecyl sulfate-polyacrylamide gel analysis. HrpI belongs to a superfamily of proteins represented by Yersinia pestis LcrD.
