Description
Albizziin is an amino acid analog with activity as a competitive inhibitor of asparagine synthetase. Albizziin has been used to isolate Chinese hamster ovary cell mutants with altered levels of the target enzyme. Several mutational classes of albizziin can be distinguished based on cross-resistance to β-aspartic hydroxamic acid. Studies on asparagine synthetase have shown that resistance to albizziin may be associated with altered regulation of asparagine synthetase, structural mutations of the enzyme, and gene amplification[1]
