Table 6 Effects of assay temperature and glucose on the S0.5 AMP for bound AMPD from skeletal muscle of control versus frozen wood frogs.

From: Regulation of 5'-adenosine monophosphate deaminase in the freeze tolerant wood frog, Rana sylvatica

  S0.5 AMP (mM)
  Control Frozen
25°C, no glucose 0.46 ± 0.03 1.50 ± 0.19
25°C, 250 mM glucose 0.30 ± 0.04 a 0.24 ± 0.03 a
5°C, no glucose 0.70 ± 0.03 a 1.77 ± 0.03 a
5°C, 250 mM glucose 0.87 ± 0.04 a 2.14 ± 0.04 a
  1. Data are means ± SEM, for determinations on Sephadex G50-filtered muscle extracts from n = 4 individual frogs. a – Significantly different from the corresponding value at 25°C without glucose as assessed by the Student's t-test, P < 0.05.
