摘要： The superfamily of short-chain dehydrogenases/reductases (SDRs) is crucial in biosynthetic and signalling pathways, in which the carbonyl reductases (CBRs) subfamily is important in the biosynthesis of tetrahydrobiopterin (BH4). BH4 is an essential coenzyme for animals, and its deficiency can lead to neurological diseases. There are few reports on CBRs involved in BH4 synthesis of silkworms, Bombyx mori. Here, we identified 67 SDR genes in B. mori (BmSDR) through whole genome survey for the first time. Based on bioinformatics analyses and KEGG verification, four BmCBRs that may be related to BH4 synthesis were further characterized and functionally analysed. The results showed these four genes were high expressed in the head and gonads of ah09 (a lem mutant with defective BH4 synthesis). Enzyme activity, BH4 content and the related gene expression levels after intracellular interference with BmCBR and the main catalytic enzymes sepiapterin reductase of B. mori (BmSpr) in the de novo pathway of BH4 showed BmCBR2 plays a role in the salvage pathway. BmCBR3 and BmCBR4 regulate BH4 synthesis through the alternative pathway. Among the four pathways of silkworm BH4 synthesis, the de novo pathway occupies the dominant position, followed by the alternative pathway and salvage pathway. According to the overexpression of BmCBR3 after interference with BmSpr, the BH4 content did not change significantly. It is speculated that BmCBR3 is located upstream of BmSpr. These results provide a theoretical basis for in-depth exploration of the role of BmSDR in B. mori and also provide clues for the research of other animal-related diseases.
