Methionine, also known as 2-amino-4-(methylthio) butanoic acid, is an amino acid, as it has one basic amino group and one acidic carboxyl group and no additional acidic or basic group on the side chain. From: Animal Nutrition, 2023 ...
Replacement of the acidic amino acid (Asp-355) or of any of the two basic amino acids (Arg-357, Arg-363) localized in the proximity of cysteine 121 by serine markedly reduced the capacity of GSNO toS-nitrosylate and inactivate liver MAT. Further, our results indicate that GSNO-induced ...

Each phosphoserine site was assigned to one of the most general kinase recognition sequence categories: (A) acidic, (B) basic, (C) Pro-directed, and (E) "others". The frequencies of each category within different subsets are shown. The considered subsets are: the whole phosphoproteome, the ...
Excision of the initiator methionine is among the first co-translational processes that occur at the ribosome. While this crucial step in protein maturation is executed by two types of methionine aminopeptidases in eukaryotes (MAP1 and MAP2), additional
2) adding basic salt or acidic salt or amphoteric salt of trace metal elements into the liquid obtained by the reaction in the step 1), further reacting, and controlling the pH value at the end point of the reaction at 5-8, thus obtaining a liquid containing a microelement methionine hydro...
In the roots of NH4 +-grown plants, the concentration and 14C-Iabeling of acidic metabolites such as citrate and malate considerably decreased whereas those of basic metabolites, especially asparagine, increased noticeably. With MSX treatment, the incorporation of 14C into basic metabolites was ...
The extract in an amount of 0.2 g as SAM was passed through a column filled with 50 ml of Amberlite IRC-50 (H+ form), a weakly acidic cation exchange resin, to cause adsorption of SAM. 0.005 N acetic acid was passed through the column to wash it until the absorbance at 260 nm of...
In Escherichia coli, the first enzyme in the methionine biosynthesis pathway, homoserine o-succinyltransferase (MetA) [1, 3–5], is extremely sensitive to many stress conditions (e.g., thermal, oxidative or acidic stress) [6–8]. At temperatures higher than 25°C, MetA activity is reduced...
Taurine and the acidic sulfur containing amino acids (cysteine sulfinic acid, cysteic acid, homocysteic acid) are not appreciable substrates (Cooper, unpublished). It is notable that Vmax values for cystine and cystathionine are comparable to those exhibited with glutamine and methionine (Ricci et al...
