CC   -!- FUNCTION: Ice nucleation proteins enable bacteria to nucleate
CC       crystallization in supercooled water.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane.
CC   -!- DOMAIN: Contains 122 imperfect repeats of a consensus octapeptide
CC       A-G-Y-G-S-T-L-T; further on a 16-residue and a regional 48-residue
CC       periodicity is superimposed.
CC   -!- BIOTECHNOLOGY: Used by snowmaking industry to promote ice
CC       nucleation for artificial snow and economize water. Sold under the
CC       name Snomax by York.
CC   -!- MISCELLANEOUS: A structural model is suggested in which the ice
CC       nucleation protein displays a symmetry related to that of ice.
CC   -!- SIMILARITY: Belongs to the bacterial ice nucleation protein
CC       family.
