Effect of natural PAL-enzyme on the quality of egg white and mushroom flour and study its impact on the expression of PKU related genes and phenylalanine reduction in mice fed on
Publication date: December 2017Source: Journal of Genetic Engineering and Biotechnology, Volume 15, Issue 2Author(s): Hesham A. Eissa, Zeinab Y. Abdallah, Wagdy K.B. Khalil, Wafaa A. Ibrahim, Hoda F. Booles, Mahrousa M. HassananeAbstractPKU patients react to therapy with a low phenylalanine diet, but adherence to this diet is troublesome, subsequently the expansion of alternative ways is demand. Phenylalanine ammonia lyase (PAL) is one of this ways, which converts phenylalanine to harmless metabolites; trans-cinnamic acid and ammonia. In the current study, the extraction of PAL enzyme was used to investigate the efficiency...

Induction of shoot regeneration in cotyledon explants of the oilseed crop Sesamum indicum L.
We present here a protocol describing plant regeneration through adventitious shoot formation from cotyledons dissected from sesame seeds soaked for four hours in water. Subculturing of the cotyledons after two weeks of culture on to a fresh Murashige and Skoog medium leads to differentiation of adventitious shoots from the proximal cut end of the explant. Culture of cotyledons on a medium containing 9% sucrose for a couple of weeks prior to transfer to MS medium supplemented with 3% sucrose induced a higher frequency of shoot regeneration. The highest frequency of 25% adventitious shoot regeneration was observed for S. in...

Computational study of putative functional variants in human kisspeptin
In this study, for the first time, KISS1 amino acid changes were discovered by tBlastn for EST database. A list of nsSNPs in human KISS1 gene from dbSNP, dbEST and UniProt databases were prepared. Computational analysis was performed using SIFT (Sorting Intolerant From Tolerant) and PolyPhen (Polymorphism Phenotyping) programs. Of the total 92 nsSNPs, 20 were found to be damaged by both servers. Six nsSNPs (P97L, G122R, W114C, R92C, R120H and N115K) are predicted with the highest damaging scores (SIFT = 0, PolyPhen = 1). These intolerant changes may suggest their functional significance in critical...
