The exonuclease1 (Exo1) gene is a key component of mismatch repair (MMR) by resecting the damaged strand, which is the only exonuclease involved in the human MMR system. The gene product is a member of the RAD2 nuclease family and functions in DNA replication, repair and recombination. However, whether Exo1 is required to activate MMR-dependent DNA damage response (DDR) remains unknown, the con...

Four hundred and eighty mixed-sex broiler chicks aged 3 hrs after hatching were allotted according to a completely random design in a 6 × 2 × 2 factorial schedule into 2 groups of 12 replications of 20 chicks each. The main experimental factors were fasting for 0, 6, 12, 24, 36, and 48 hrs after chick placement, calcium gluconate (Ca-glu) injection (0 and 0.6 mL) and sex (male and female). Inde...

In this work, biodegradable macroporous stimuli-responsive polypeptide hydrogels based on l-glutamic acid (Glu) and its copolymers with equimolar amounts of l-phenylalanine (Phe) or l-lysine (Lys) were prepared by deprotection the corresponding organogels under acidic conditions. The synthesized ring-opening polymerization N-carboxyanhydride (NCA) derivatives ?-amino acids in oil-in-oil high-in...

High molecular weight glutenin subunits (HMW-GSs) play a major role in determining the dough quality of wheat. As D genome donor hexaploid wheat, Aegilops tauschii is an important genetic resource for wheat breeding. In present study, novel HMW-GSs from Ae. was identified and designated as Glu-Dt1. Multiple sequence alignment indicated that one cysteine mutated into arginine y-type subunit. Sit...

We investigated the relationships of three allelic variations in Glu-B3 (ab, g, and h) with dough properties and bread-making quality-related characteristics using near-isogenic lines (NILs) of 'Yumechikara' that commonly carry Glu-A1a, Glu-B1b, Glu-D1d, Glu-A3f, Glu-B3ab and Glu-D3a. Measurement of peak time (PT) in a 2-g mixograph indicated that Glu-B3g was the most effective for a strong dou...

The hexapeptides AcSer-Glu-Glu-Glu-Val-Glu and Ser-Glu-Glu-Glu-Glu-Glu, reminiscent of the sites phosphorylated by type-2 casein kinase TS in troponin T and glycogen synthase, respectively, have been synthesized and tested as phosphorylatable substrates for casein kinase TS as well as for other protein kinases. Both peptides are readily phosphorylated by casein kinase TS but not, to any detecta...
