Neutral ceramidase B also known as non-lysosomal ceramidase B or N-acylsphingosine amidohydrolase (non-lysosomal ceramidase) 2B or ASAH2B is a
ceramidase
Ceramidase (, ''acylsphingosine deacylase'', ''glycosphingolipid ceramide deacylase'') is an enzyme which cleaves fatty acids from ceramide, producing sphingosine (SPH) which in turn is phosphorylated by a sphingosine kinase to form sphingosine- ...
enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products ...

gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...
