Pyruvate kinase of Streptococcus mutans JC 2 had an absolute and specific requirement for glucose-6-phosphate. Inorganic phosphate was a strong inhibitor. The enzyme required K+ or NH4+ and Mg2+ or Mn2+. S. mutans FIL and E 49, Streptococcus bovis ATCC 9809, and Streptococcus salivarius ATCC 13419 had also glucose-6-phosphate-dependent pyruvate kinases, whereas Streptococcus sanguis NCTC 10904 had an enzyme activated by fructose-1,6-diphosphate.
变形链球菌JC 2的丙酮酸激酶对6-磷酸葡萄糖有绝对且特异的需求。无机磷酸盐是一种强抑制剂。该酶需要K⁺或NH₄⁺以及Mg²⁺或Mn²⁺。变形链球菌FIL和E 49、牛链球菌ATCC 9809以及唾液链球菌ATCC 13419也有依赖6-磷酸葡萄糖的丙酮酸激酶，而血链球菌NCTC 10904有一种由1,6-二磷酸果糖激活的酶。
