AMARA peptide
Based on 1 publication(s) in Google Scholar
AMARA peptide is a synthetic peptide substrate of sucrose non-fermenting-1-related protein kinase 1 (SnRK1). AMARA peptide contains residues required for SnRK1 phosphorylation, retains the minimal motif recognized by SnRK1, and when this substrate is recognized by cauliflower SnRK1 HRK-A, the hydrophobic residues at the relative positions P-5 and P+4 of the phosphorylated serine require a critical spacing. AMARA peptide can serve as a control substrate in peptide phosphorylation assays for the detection of SnRK1 activity in Arabidopsis thaliana, potato tuber tissues, and during SnRK1 purification.

In Vitro
AMARA peptide TFA is phosphorylated by crude soluble protein extracts from liquid-cultured Arabidopsis thaliana (Col-4) seedlings with a calcium-independent activity of 2.49 nmol/min/mg, 90% of which is attributable to SnRK1, plus a small additional calcium-dependent activity[1].
The AMARA peptide TFA functions as an improved synthetic substrate for plant SnRK1 compared to the SAMS peptide[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Peptide Solubility and Storage Guidelines:
1. Calculate the length of the peptide.
2. Calculate the overall charge of the entire peptide according to the following table:
| Contents | Assign value | |
|---|---|---|
| Acidic amino acid | Asp (D), Glu (E), and the C-terminal -COOH. | -1 |
| Basic amino acid | Arg (R), Lys (K), His (H), and the N-terminal -NH2 | +1 |
| Neutral amino acid | Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) | 0 |
3. Recommended solution:
| Overall charge of peptide | Details |
|---|---|
| Negative (<0) |
1. Try to dissolve the peptide in water first. 2. If water fails, add NH4OH (<50 μL). 3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide. |
| Positive (>0) |
1. Try to dissolve the peptide in water first. 2. If water fails, try dissolving the peptide in a 10%-30% acetic acid solution. 3. If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO. |
| Zero (=0) |
1. Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first. 2. For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration. |
