LDH (Lactate dehydrogenase) enzyme catalyzes the reversible conversion of pyruvate to lactate using NAD+ as a cofactor. Although the physiological significance of lactate accumulation in tumor cells, a dead-end product in cellular metabolism, is currently a topic of debate, it has long been known that many tumor cells express a high level of LDH-A (Koukourakis et al., 2003; Koukourakis et al., 2006; Koukourakis et al., 2009). So detection of its enzyme activity in vitro is important for researching on LDH-A. Recently, it has been reported that Lys-5 acetylation could decrease LDH-A enzyme activity (Zhao et al., 2013).
