中文摘要 | Allophycocyanin (APC) is widely used as a fluorescent tag for fluorescence detection techniques. In this study, the alpha pcB gene from a thermophilic cyanobacterium strain was cloned and ligated into an expression vector to construct a pathway for the biosynthesis of an allophycocyanin beta subunit (holo-apcBT) in Escherichia coli. Isopropyl beta-D-1-thiogalactopyranoside induction successfully reconstituted holo-apcBT in E. coli. The recombinant holo-apcB showed spectroscopic properties similar to native APC. The stability and spectroscopic properties of this protein were then compared with another recombinant allophycocyanin beta subunit (holo-apcBM) whose apcB gene was cloned from mesophilic cyanobacterium. At high temperatures and during the course of storage, holo-apcBT was significantly more stable than holo-apcBM. In addition, holo-apcBT had an unexpectedly higher extinction coefficient and fluorescence quantum yield than holo-apcBM, suggesting that holo-apcBT would be a promising fluorescent tag and serve as a substitute for native APC.
