Phenylalanine Ammonia-lyase of Bamboo Shoots [PDF]

Agricultural and Biological Chemistry, 1988
Phenylalanine ammonia-lyase (PAL) was purified from bamboo shoots (Bambusa oldhami Munro) through steps of DEAE-Sephacel column chromatography, Sepharose CL-6B gel filtration, and a second DEAE-Sephacel column chromatography. Polyacrylamide gel electrophoresis showed that the purified enzyme (Mr 360, 000) still contained two minor bands with much ...

Fungal and Plant Phenylalanine Ammonia-lyase [PDF]

Mycobiology, 2011
L-Phenylalanine is one of the essential amino acids that cannot be synthesized in mammals in adequate amounts to meet the requirements for protein synthesis. Fungi and plants are able to synthesize phenylalanine via the shikimic acid pathway. L-Phenylalanine, derived from the shikimic acid pathway, is used directly for protein synthesis in plants or ...

Heterologous caffeic acid biosynthesis in Escherichia coli is affected by choice of tyrosine ammonia lyase and redox partners for bacterial Cytochrome P450

Microbial Cell Factories, 2020
Background Caffeic acid is industrially recognized for its antioxidant activity and therefore its potential to be used as an anti-inflammatory, anticancer, antiviral, antidiabetic and antidepressive agent.

RidA proteins prevent metabolic damage inflicted by PLP-dependent dehydratases in all domains of life [PDF]

, 2013
Pyridoxal 5′-phosphate (PLP) is a coenzyme synthesized by all forms of life. Relevant to the work reported here is the mechanism of the PLP-dependent threonine/serine dehydratases, which generate reactive enamine/imine intermediates that are converted to
