Protein
Neutral ceramidase
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Function
Catalyzes the cleavage of the N-acyl linkage of the ceramides (Cers) to yield sphingosine (Sph) and free fatty acid. Also catalyzes the synthesis of Cers from Sph and fatty acid. Cers containning C6-C24 fatty acids are well hydrolyzed, and Cers with mono unsaturated fatty acids are much more hydrolyzed than those with saturated fatty acids.
Similarity
Belongs to the neutral ceramidase family.
