EC 4.1.1.64     
Accepted name: 2,2-dialkylglycine decarboxylase (pyruvate)
Reaction: 2,2-dialkylglycine + pyruvate = dialkyl ketone + CO2 + L-alanine
Other name(s): dialkyl amino acid (pyruvate) decarboxylase; α-dialkyl amino acid transaminase; 2,2-dialkyl-2-amino acid-pyruvate aminotransferase; L-alanine-α-ketobutyrate aminotransferase; dialkylamino-acid decarboxylase (pyruvate); 2,2-dialkylglycine carboxy-lyase (amino-transferring)
Systematic name: 2,2-dialkylglycine carboxy-lyase (amino-transferring; L-alanine-forming)
Comments: A pyridoxal-phosphate protein. Acts on 2-amino-2-methylpropanoate (i.e. 2-methylalanine), 2-amino-2-methylbutanoate and 1-aminocyclopentanecarboxylate.
