ADH3
ADH3 is an amidohydrolase derived from Stenotrophomonas acidaminiphila and forms an octamer in solution. ADH3 was reported to exhibit 57- to 35,000-fold higher activity than other enzymes and is the most efficient OTA-detoxifying enzyme reported thus far and can hydrolyze OTA to nontoxic ochratoxin α (OTα) and L-β-phenylalanine (Phe). Moreover, soluble protein expression of ADH3 in Escherichia coli has been realized.

Because of its high efficiency and soluble expression in Escherichia coli , we used the variant S88E of ADH3 engineered by Xiong L et al. (2023) in our project to degrade OTA.
