General annotation (Comments)

Function

Ice nucleation proteins enable bacteria to nucleate crystallization in supercooled water.

Subcellular location

Cell outer membrane.

Domain

Contains 122 imperfect repeats of a consensus octapeptide A-G-Y-G-S-T-L-T; further on a 16-residue and a regional 48-residue periodicity is superimposed.

Biotechnological use

Used by snowmaking industry to promote ice nucleation for artificial snow and economize water. Sold under the name Snomax by York.

Miscellaneous

A structural model is suggested in which the ice nucleation protein displays a symmetry related to that of ice.

Sequence similarities

Belongs to the bacterial ice nucleation protein family.
