A Phenylalanine Ammonia Lyase Capacitive Sensor for Phenylalanine Detection
In this paper, an easy-to-use and fast biosensor for phenylalanine quantification in patients affected by phenylketonuria is investigated. The phenylalanine concentration was indirectly estimated through the ammonia released as a by-product of an ...

IMMOBILIZATION OF PHENYLALANINE AMMONIA-LYASE ON HYDROXYAPATITE AND HYDROXYAPATITE COMPOSITES
A new and efficient immobilization method of phenylalanine ammonia-lyase was obtained using hydroxyapatite (HAP) and hydroxyapatite - carbon nanotube, gelatin and chitosan - composites (HAP-CNT, HAP-GEL and HAP-CS) as support material.

Phenylalanine Ammonia-lyase of Bamboo Shoots [PDF]
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 ...

Erythrocytes as Carriers of Therapeutic Enzymes. [PDF]
Therapeutic enzymes are administered for the treatment of a wide variety of diseases. They exert their effects through binding with a high affinity and specificity to disease-causing substrates to catalyze their conversion to a non-noxious product, to ...

Maize Phenylalanine Ammonia-Lyase Has Tyrosine Ammonia-Lyase Activity [PDF]
Abstract A full-length cDNA encoding phenylalanine ammonia-lyase (PAL) from Zea mays L. was isolated and the coding region was expressed in Escherichia coli as a C-terminal fusion to glutathione S-transferase. After purification by glutathione-Sepharose chromatography, the glutathione S-transferase moiety was cleaved off and the ...

Molecular genetics of naringenin biosynthesis, a typical plant secondary metabolite produced by Streptomyces clavuligerus [PDF]
Background: Some types of flavonoid intermediates seemed to be restricted to plants. Naringenin is a typical plant metabolite, that has never been reported to be produced in prokariotes.

ENDOPHYTIC BACTERIA ASSOCIATED WITH SUGARCANE AND ITS POTENTIAL TO SUPPRESS SPORISORIUM SCITAMINEUM, THE CAUSAL FUNGAL PATHOGEN OF SMUT DISEASE [PDF]
Bacterial endophytic ubiquitously colonize the internal tissues of the plant. The purpose of this study was to isolate and identify the endophytic bacteria from sugarcane stalks which have antagonistic activity against Sporisorium scitamineum, the causal
