the cysteines. Disulfide bonds are important in protein structure because they allow the linkage of two different parts of a protein molecule to—and thus the formation of loops in—the otherwise straight chains. Some proteins contain small amounts of cysteine with free sulfhydryl (―SH) groups....
Antioxidant peptides are generally composed of 3–16 amino acid residues, and their main components are histidine or tyrosine residues, as well as methionine, cysteine, tryptophan and lysine, which also exhibit antioxidant activity in free form (Sánchez & Vázquez, 2017). There are a number of...
Screening rearranged alleles at theγ27locus occurring at meiosis based on phenotype is impossible, because a single copy of this gene is sufficient to maintain the vitreous phenotype in normal maize kernels29. A reduction of γ27 affects endosperm modification in QPM, causing an opaque phenotype i...
differentiation from closely relatedB. cereusin powder samples, with a limit of detection of 2.5 × 106spores46. Ten distinct pathogenic bacterial samples includingB. anthracisandY. pestiswere used in an inter-laboratory ring trial from nine European countries: accurate microbial identification ...
(d) genipin powder was added in the mixture with stirring to reach a concentration of 10 mM; (e) the mixture was put in a 25 °C constant water bath with stirring for 12 h; (f) three times volume of absolute ethanol was added in the mixture for terminating the reaction; (g) the ...
Detailed parameters are listed as follows: Precursor Ion Tolerance, 20 ppm; Fragment Ion Tolerance, 0.02 Da; Maximum Missed Cleavages, 2; Static Modifications, cysteine (C) carbamidomethylation, peptide N-terminal TMT; Dynamic Modifications, methionine (M) oxidation, serine (S)/threonine (T) ...
Methionine oxidation and N-terminal acetylation as well as a carbamidomethylation at cysteine residues were considered as variable and fixed modifications, respectively. First, an initial search was carried out using a precursor mass tolerance of 20 ppm and after recalibration, a second search was ...
