Abstract:
A lag phase in the spectrophotometric assay progress curve of aldehyde oxidation by HL-ADH was observed and characterised. The aldehyde oxidation and aldehyde dismutation reactions were shown to be related, and a mechanism to explain net aldehyde oxidation was proposed. The spectrophotometric assay was shown to be unsuitable for measurement of kinetic parameters for aldehyde oxidation by HL-ADH, and kinetic constants previously determined were shown to be in error. Existing data on the aldehyde dismutation reaction are insufficient to discount a role for HL-ADH in aldehyde transformation in vivo.
