The first identification and characterization of a prokaryotic gene (spsA) encoding sucrose-phosphate synthase (SPS) is reported for Synechocystis sp. strain PCC 6803, a unicellular non-nitrogen-fixing cyanobacterium. Comparisons of the deduced amino acid sequence and some relevant biochemical properties of the enzyme with those of plant SPSs revealed important differences in the N-terminal and UDP-glucose binding site regions, substrate specificities, molecular masses, subunit compositions, and regulatory properties.
报道了单细胞非固氮蓝藻集胞藻PCC 6803中编码蔗糖磷酸合酶(SPS)的原核基因(spsA)的首次鉴定和特性分析。该酶推导的氨基酸序列及一些相关生化特性与植物SPSs的比较显示,在N端和UDP-葡萄糖结合位点区域、底物特异性、分子量、亚基组成及调控特性方面存在重要差异。
