Stable Suppression of Lactate Dehydrogenase Activity during Anoxia in the Foot Muscle of Littorina littorea and the Potential Role of Acetylation as a Novel Posttranslational Regulatory Mechanism

Table 3

The effects of salts, common denaturants, and temperature on control and 24 h anoxic L. littorea foot muscle LDH.

	Control	24 h anoxic
NaCl 𝐼50 (M)	0.79±0.03	0.79±0.03
KCl 𝐼50 (M)	0.97±0.04	0.81±0.02^∗
Urea 𝐼50 (M)	3.1±0.1	3.1±0.2
GnHCl 𝐼50 (M)	0.384±0.007	0.40±0.01
𝑇𝑚 (°C)	51.9±0.3	50.0±0.1^∗

The data are means ± SEM, 𝑛≥3 independent determinations on individual enzyme preparations. *indicates that the 24 h anoxic value is significantly different from the corresponding control value using Student’s 𝑡-test, 𝑃<0.05.
