Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Degrades the rhamnogalacturonan I (RG-I) backbone of pectin. Is required for the full virulence of E.chrysanthemi strain 3937 as it is involved in rotting of plant tissue.
Catalytic activity	Cleaves the alpha-1,4 linkage of RG-I backbone between a rhamnose and a galacturonate, thereby creating an unsaturated bond between carbons 4 and 5 of the galacturonate residue.
Subcellular location	Secreted. Note: Via the type II out secretion pathway.
Induction	By rhamnose.
Miscellaneous	Contrary to other proteins secreted by the Out pathway, rhiE contains no disulfide bond.
Sequence similarities	Belongs to the polysaccharide lyase 4 family.
Caution	Both Met-1 and Met-3 seem to be able to act as initiation codons.
biophysicochemical properties	pH dependence: Optimum pH is 6.0.
