Photoactive yellow protein-based protein labeling system with turn-on fluorescence intensity.

J. Am. Chem. Soc. 131 , 16610-16611, (2009)

Protein labeling provides significant information about protein function. In this research, we developed a novel protein labeling technique by utilizing photoactive yellow protein (PYP). PYP is a smal...

Induction of 4-hydroxycinnamate decarboxylase in Klebsiella oxytoca cells exposed to substrates and non-substrate 4-hydroxycinnamate analogs.

Biosci. Biotechnol. Biochem. 65 , 2604-2612, (2001)

The 4-hydroxycinnamate decarboxylase (4-HCD)-inducing activity of several substrate analogs toward Klebsiella oxytoca was investigated. Four E-cinnamate-class compounds, E-4-hydroxycinnamic acid (1), ...
