AMARA peptide TFA
Based on 1 Customer Validation
AMARA peptide TFA is a synthetic peptide substrate of sucrose non-fermenting-1-related protein kinase 1 (SnRK1). AMARA peptide TFA 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 TFA 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.

SnRK1 |
In Vitro
AMARA peptide TFA is potently phosphorylated by purified spinach SnRK1 in vitro with a specific activity of 142 nmol/min/mg[1].
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].
