“…35% of the amino acid profile; the only other amino acid that approached 10% was arginine (Table 2). These results are similar to amino acid profiles reported previously (Oupadissakoon et al, 1980;Pancholy et al, 1978;Young et al, 1973;Young, 1979). Significant differences were recorded for all amino acids.…”

“…Peanuts are a rich source of nonmeat protein and average between 22 and 30% protein (Pancholy et al, 1978;Young et al, 1973). Amino acid profiles of peanut are not well balanced, with certain essential amino acids occurring in limiting concentration when compared to FAO (1990) recommended levels.…”

“…Pancholy et al (1978) studied the amino acid composition of 19 cultivars and breeding lines of peanuts and concluded that lysine, methionine, and threonine were probably represented in limiting concentrations. Young et al (1973) expanded the list to also include isoleucine and valine. However, nearly a twofold variation in the limiting essential amino acids has been reported (Oupadissakoon et al, 1980;Young et al, 1973;Young, 1979).…”

However, nearly a twofold variation in the limiting essential amino acids has been reported (Oupadissakoon et al, 1980;Young et al, 1973;Young, 1979). Basha et al 1980 suggested that since substantial genetic variability exists in protein synthesis characteristics of different peanut cultivars, there may be ample justification to select for peanuts with favorable amino acid profiles.…”

“…Therefore, the biosynthesis of the glycerate-3-phosphate group of amino acids competed with the biosynthesis of all the other amino acids; the competition resulted to the very low concentrations of cysteine, serine, and glycine irrespective of the mineral ion treatment of the peanut ( Table 2). Analyses of total amino acid contents of 16 varieties of peanuts showed that ser, gly, and cys together were the lowest in concentration [49].…”

Lack of essential amino acids (EAA) in the diet of at-risk populations could beget a state of food insecurity. Plant proteins are deficient in some essential amino acids. Animals obtain EAA from plant sources. Simple biotechnologies are being developed for improving the EAA composition of crop proteins. The aim was to integrate-discriminate glycolysis and citric-glyoxylic acid cycles to optimize biosynthesis of EAA in food crops. Permutation of diverse metabolic pathways at the mRNA level by glutamate dehydrogenase (GDH)-synthesized RNA is a common biotechnology for doubling the nutritious compositions of plants. Peanuts were planted in plots and treated with mineral salts mixed according to stoichiometric ratios. Protein-bounded and free amino acids of mature peanut seeds were determined by HPLC. GDH-synthesized RNA probes homologous to the mRNAs encoding glyceraldehyde-3-phosphate dehydrogenase (GAPDH), phosphoglycerate mutase (PGlycM), phosphoenolpyruvate carboxylase (PEPCase), enolase, malate dehydrogenase (MDH), isocitrate lyase (ICL), and malate synthase (MS) were prepared from peanut seeds using restriction fragment double differential display PCR method. Northern assays of peanut total RNA showed that the mRNAs encoding PGlycM, PEPCase, MDH, and MS shared extensive sequence homologies that produced a dense network of cross-talks, resulting to co-differential silencing of the mRNAs thereby permuting glycolysis, citric-glyoxylic acid cycles. There were 42 permutations in the NPPKtreated, 105 in control, 420 in KN-, and NPKS-treated peanuts. Because of permutations involving the mRNAs encoding ICL and MS, wherever the abundances of these mRNAs were high (control, and NPPK-treated peanuts) the concentrations of the α-ketoglutarate group of total glutamate, glutamine, arginine, proline, and histidine were minimized (<7.0 mg/g) but the concentrations of the oxaloacetate group of total aspartate, lysine, methionine, threonine, and isoleucine were maxi-* Corresponding author. G. O. Osuji et al.3092 mized (>28.0 mg/g). The integration of glycolysis, citric and glyoxylic acid cycles increased the quality and doubled the concentrations of the protein-bounded EAA composition of NPPK-treated (33.37 mg/g) compared with the control peanut (15.66 mg/g). The commanding biotechnology was the stoichiometric mineral salts-based induction of GDH to synthesize the RNAs that integrated glycolysis, citric-glyoxylic acid cycles to one functional unit.

Seed protein characterisation and nitrogen fixation rates in the chickpea mutant hyprosola and its parent

et al. 1988

The amino acid composition of the seed proteins of Hyprosola, a high protein, high yielding mutant of chickpea (Cicer arietinum L), differed little from that of its parental cultivar, Faridpur-I. Oser's essential amino acid index was 76.5 in the mutant and 76.7 in the parent. Hyprosola seed has higher crude protein, extractable protein, globulin and albumin contents than Faridpur-1. The mutant had an albumin/globulin ratio of 0.23 compared with the parental value of 0.21. The mutant oligomeric proteins differed quantitatively and qualitatively from the parent on cellulose acetate electrophoretograms. The polypeptide composition of globulins and albumins fractionated by SDS-PAGE differed markedly in the intensity of many bands but not in the mobility of any polypeptides. Nitrogen fixation (acetylene reduction) rates were similar in the two cultivars, and in both hydrogen evolution utilised 45 % of the electron flow through nitrogenase.
