Protein Variants

EC Number	Protein Variants	Comment	Organism
4.2.2.26	H178A	mutant shows reduced oligoalginate lyase activity	Sphingomonas sp.
4.2.2.26	H389A	mutant shows reduced oligoalginate lyase activity	Sphingomonas sp.
4.2.2.26	N177A	mutant shows reduced oligoalginate lyase activity	Sphingomonas sp.
4.2.2.26	R236A	mutant exhibits endolytic activity. The overexpressed mutant protein (79.6 kDa) is proteolytically cleaved into the N-terminal 32.0-kDa and the C-terminal 47.6-kDa fragments. Both fragments show endolytic lyase activity	Sphingomonas sp.
