Mt. Apo was first climbed on October 10, 1880 by a party led by Don Joaquin Rajal.
Mount Apo is one of the most popular climbing destinations in the country. The summit is very easy to reach, unlike other mountains such as Mount Halcon and Mount Banahaw. On May 9, 1936, Mount Apo was declared a national park by President Manuel L. Quezon. The mountain is home to over 270 bird species, with more than a hundred that are endemic.
Effect of GSH and modification of lysines on ATP binding to MT. ATP (100 µM) was incubated with rabbit Cd,Zn-MT-2 (142 µM) in 50 mM Hepes·NaOH (pH 7.4) in the absence of GSH or in the presence of either GSH (120 µM) or GSSG (500 µM) (4).
Reactivity of thiols of MT in the absence and presence of ATP.
The shape of the MT molecule is that of a prolate ellipsoid (dumbbell) and thus deviates significantly from that of a globular
MT (0.24 µM) (molar ratio between zinc and apo-SDH of 1.0) was incubated with apo-SDH (1.7 µM) in 0.2 M Tris·HCl, pH 7.4, in the presence of GSSG and/or GSH.
MT (0.24 µM) was incubated with apo-SDH (1.7 µM) in 0.2 M Tris·HCl, pH 7.4, for 60 min at the indicated concentrations of GSH and GSSG.
MT (1.3 µM) was incubated with PAR (100 µM) in 0.2 M Tris·HCl, pH 7.4, in the presence of increasing amounts of GSH, and the reaction was followed by measuring the increase of absorbance at 500 nm of the zinc-PAR complex for 60 min.
