KEGG ENZYME: 3.1.1.78

ENZYME: 3.1.1.78

Entry

EC 3.1.1.78                 Enzyme

Name

polyneuridine-aldehyde esterase;
polyneuridine aldehyde esterase;
PNAE

Class

Hydrolases;
Acting on ester bonds;
Carboxylic-ester hydrolases

Sysname

polyneuridine aldehyde hydrolase (decarboxylating)

Reaction(IUBMB)

polyneuridine aldehyde + H2O = 16-epivellosimine + CO2 + methanol [RN:R05825]

Reaction(KEGG)

R05825

Substrate

polyneuridine aldehyde [CPD:C11632];
H2O [CPD:C00001]

Product

16-epivellosimine [CPD:C11633];
CO2 [CPD:C00011];
methanol [CPD:C00132]

Comment

Following hydrolysis of this indole alkaloid ester the carboxylic acid decarboxylates spontaneously giving the sarpagan skeleton. The enzyme also acts on akuammidine aldehyde (the 16-epimer of polyneuridine aldehyde).
