FIG. 2.

Alignment of HrpW with pectate lyases of N. haematococca mating type VI (F. solani f. sp. pisi) and of E. carotovora subsp. carotovora. The sequences were aligned by the PILEUP program (GCG software package, version 7.3) with default parameters, and the alignment was manually edited by using the LINEUP program in the same package. Conserved residues are boxed, highly conserved regions are underlined, and conserved Cys residues are indicated by asterisks. Shaded regions in HrpW may form α-helices.
