Antimicrobial peptides (AMPs) are effective against different plant pathogens and newly considered as part of plant defense systems. From prokaryotes to eukaryotes, AMPs can exist in all forms of life. SM-985 is a cationic AMP (CAMP) isolated from the cDNA library of Mexican teosinte (Zea
Benzoyl-L-arginine p-nitroanilide hydrolase in the etiolated leaves of Zea mays L. has been purified 1,266-fold by a combination of gel filtration, ion exchange, and hydrophobic chromatography with a recovery of 13%. The specific activity of the purified enzyme is 5.7 units/mg protein. The enzyme is
Endothelial cell dysfunction (ECD) is a common feature of hypercholesterolemia. Defective nitric oxide (NO) generation due to decreased endothelial nitric oxide synthase (eNOS) activity is a crucial parameter characterizing ECD. L-arginine is the sole precursor for NO biosynthesis. Among several
The complete sequence of a mitochondrial DNA insertional event containing the 3' portion of the chloroplast 23S-4.5S rRNA gene, the entire 5S rRNA gene and intervening sequence and all but the 3' 6 nucleotides of the arginine tRNA gene is reported. Also reported are both chloroplast/mitochondrial
Heavy metals pollution is one of the key environmental problems. In this research, the effect of seed priming with salicylic acid and sodium hydrosulfide was investigated on methionine and arginine amino acids contents and some compounds derived from their metabolism as well as ZmACS6 and ZmSAMD
The maize RNA-binding MA16 protein is a developmentally and environmentally regulated nucleolar protein that interacts with RNAs through complex association with several proteins. By using yeast two-hybrid screening, we identified a DEAD box RNA helicase protein from Zea mays that interacted with
C(4)-specific (photosynthetic) NADP(+)-dependent malic enzyme (NADP(+)-ME) has evolved from C(3)-malic enzymes and represents a unique and specialized form, as indicated by its particular kinetic and regulatory properties. In the present paper, we have characterized maize (Zea mays L.)
Three dicarbonyl reagents were used to demonstrate the presence of an essential arginine residue in the NO(3) (-) uptake system from corn seedling roots (Zea mays L., Golden Cross Bantam). Incubation of corn seedlings with 2,3-butanedione (0.125-1.0 millimolar) and 1,2-cyclohexanedione (0.5-4.0
In the present study, three experiments were conducted to investigate the effect of oral supplementation of l-arginine (ARG) on the disposal of glucose in stressed-broiler chickens (Gallus gallus domesticus). In all the three experiments, the broiler chickens were randomly subjected to one of the
1H, 13C NMR, ESMS and MS/MS investigations proved that there is an antagonism in the spontaneous reaction of formaldehyde with L-lysine and L-arginine. L-Arginine can only be hydroxymethylated on the guanidino group in a very fast reaction forming mono-, di-, and trihydroxymethyl arginines (HMA).
In extracts from the youngest leaves of Avena sativa, Hordeum vulgare, Zea Mays, Pisum sativum, Phaseolus vulgaris, Lactuca sativa, and four pyrrolizidine alkaloid-bearing species of Heliotropium, the activities of ornithine decarboxylase, close to V(max), ranged between traces and 1.5 nanomoles per
Estrogen (17beta-estradiol, or E2) reduces systolic blood pressure (SBP) increment and increases aortic cyclic guanosine monophosphate (cGMP) in male spontaneously hypertensive rats (SHRs). It is unknown, however, whether the E2-enhanced aortic cGMP is essential for the BP-lowering effect or not.
In this study, changes in DNA transcription activity are presented during parenchymal cell differentiation of the primary cortex of roots of a species with elevated DNA content in which endomitotic polyploidization does not occur (Tulipa kaufmanniana), as well as a species with low content levels in
In excised pro(1-1) mutant and corresponding normal type roots of Zea mays L. the uptake and interconversion of [(14)C]proline, [(14)C]glutamic acid, [(14)C]glutamine, and [(14)C]ornithine and their utilization for protein synthesis was measured with the intention of finding an explanation for the
Plant glycine-rich RNA-binding proteins (GRRBPs) contain a glycine-rich region at the C-terminus whose structure is quite unknown. The C-terminal glycine-rich part is interposed with arginine and tyrosine (arginine/glycine/tyrosine (RGY)-rich domain). Comparative sequence analysis of forty-one
