PURIFICATION AND PROPERTIES OF RAT GASTROCNEMIUS MUSCLE N-ACETYL-I3-DGLUCOSAMINIDASE A AND B.
N-acetyl-B-D-Glucosaminidase was purified by affinity and ionexchange chromatography. Two major, A and B, and three minor intermediate forms were isolated and characterized. NAG-A and NAG-B were purified 440 and 1200 fold with final yields of 16 and 23 percent respectively. Each activity was represented by a single protein band. After 70 min preincubation at 55°C a loss of70% activity of N...

متن کاملIonic N-B-N- and B-N-B-substituted benzene analogues: a theoretical analysis.
Calculations are presented on six-π-electron N-B-N- and B-N-B-substituted benzene rings, [C(3)BN(2)H(6)](+) and [C(3)NB(2)H(6)](-), and their isomers. These compounds display a wide range of thermodynamic stability in those molecules, with N-B-N connectivity favored strongly in the cation, B-N-B in the anion. That stability order is easily understood using the charge distribution in a benzene p...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
