There are four metabolic pathways for 4HBA: protocatechuate cleavage pathway; catechol cleavage pathway; anaerobic degradation pathway in anaerobes ; and gentisate cleavage pathway. The last pathway including a NIH shift reaction remains to be elucidated. In this review we emphasized on the NIH shift reaction involved in the 4HBA degrdation. The key enzymes of each 4HBA metabolic pathway also were introduced. Finnaly, we described the thermophilic Bacillus sp. B1 strain which was capable of degrading varous aromatic compounds including gHBA, and presented a direction for the research of NIH shift reaction.展开更多
