Crustacean oxi-reductases protein sequences derived from a functional genomic project potentially involved in ecdysteroid hormones metabolism – A starting point for function examination.

Highlights: [•] Transcript assembly of crustacean epithelium was constructed and characterized. [•] Proteins potentially related to ecdysteroid hormones metabolism were characterized. [•] Identifying potential 3-beta-SDRs related to ecdysteroid modification. [•] Identifying potential 3-oxo-delta-4 steroid 5-beta reductases related to ecdysteroidogenesis. [•] Identifying 7-DHCR rarely demonstrated in arthropods. [ABSTRACT FROM AUTHOR]
