US 6,830,915 B2 · Glycosyl hydrolase genes and their use for producing enzymes for the biodegradation of carrageenans

Abstract

The present invention relates to genes which code for glycosyl hydrolases having an HCA score with the iota-carrageenase of Alteromonas fortis which is greater than or equal to 65% over the domain extending between amino acids 164 and 311 of the protein sequence SEQ ID No. 2 of said iota-carrageenase, and to genes which code for glycosyl hydrolases having an HCA score with the kappa-carrageenase of Alteromonas carrageenovora which is greater than or equal to 75% over the domain extending between amino acids 117 and 262 of the protein sequence SEQ ID No. 6 of said kappa-carrageenase.
