Well structured: As a new triose phosphate isomerase (TIM) barrel-fold prenyl transferase, PcrB catalyzes the production of heptaprenylglyceryl phosphate from heptaprenyl diphosphate and glycerol-1-phosphate. Crystal structures of PcrB from Bacillus subtilis and Staphylococcus aureus in complex with ligands were solved, and together with site-directed mutagenesis and bioinformatics analyses, clearly reveal the catalytic mechanism of the enzyme.
作为一种新型的磷酸丙糖异构酶(TIM)桶状 prenyl 转移酶,PcrB 催化从七异戊二烯二磷酸和甘油-1-磷酸生成七异戊烯基甘油磷酸。已解析出枯草芽孢杆菌和金黄色葡萄球菌 PcrB 与配体复合物的晶体结构,并结合定点突变和生物信息学分析,清楚地揭示了该酶的催化机制。
