Elicitins are a family of small, highly-conserved proteins secreted by phytopathogenic fungi belonging to the phytophthora species [PubMed7753775]. They are toxic proteins reponsible for inducing a necrotic and systemic hypersensitive response in plants from the solanaceae and cruciferae families. Leaf necrosis provides immediate control of fungal invasion and induces systemic acquired resistance; both responses mediate basic protection against subsequent pathogen inoculation.

Members of this family share a high level of sequence similarity, but they differ in net charge, dividing them into two classes: alpha and beta [PubMed7753775]. Alpha-elicitins are highly acidic, with a valine residue at position 13, whereas beta-elicitins are basic, with a lysine at the same position. Residue 13 is known to be involved in the control of necrosis and, being exposed, is thought to be involved in ligand/receptor binding [, PubMed9385630]. Phenotypically, the two classes can be distinguished by their necrotic properties: beta-elicitins are 100-fold more toxic and provide better subsequent protection [PubMed7753775].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.

Alignments of sequences to 2 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

Browse and view proteins in genomes which have different domain combinations including a Fungal elicitin domain.

Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.

Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 2 hidden Markov models representing the Fungal elicitin superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
