Description
Lactate dehydrogenase from rabbit muscle can be inhibited by ascorbate. Aldolase and actin were shown to block this inhibitory effect. Pyruvate kinase requires bivalent and monovalent cations such as Mg2+ and K+ respectively for activation to occur.

PK/LDH enzymes, Native (Rabbit)
Applications
Pyruvate kinase from rabbit muscle has been used in a study to assess nuclear magnetic relaxation studies of the conformation of adenosine 5′-triphosphate. It has also been used in a study to investigate heterogeneity of presumably homogeneous protein preparations.
Product Overview
Pyruvate kinase from rabbit muscle catalyzes an ATP-dependent phosphorylation of glycolate to yield 2-phosphoglycolate. buffered aqueous glycerol solution, 900-1400 units/mL lactic dehydrogenase, 600-1 kDa units/mL pyruvate kinase
