A transaminase (aminotransferase, EC 2. 6. 1) was extracted and
purified approximately 148-fold from shoot tips of pea (Pisum sativum
L. cv. Alaska) seedlings and some properties of the enzyme were
determined. The purification included acetone precipitation followed
by column chromatography on hydroxylapatite.
With a-ketoglutarate as co-substrate, the acetone precipitated...
C-methyltransferase
(HIOMT) in chinook salmon (Oncorhynchus
tshawytscha). Various body tissues, as well as several
morphological brain divisions were tested for the presence
of HIOMT. Activity was found in the retina, the dorsal
portion of the diencephalon, and in the pineal gland of
chinook. However, the activity was significantly higher
in...
The purpose of this investigation was to determine if the level
of aspiration procedure consisting of knowledge of results plus goal-setting
possesses a motivational property as reflected in performance
on subject matter criterion instruments above that of knowledge of
results alone in an undergraduate biology course. In addition the
