Biological Activity

Description

Beta-Asp-Arg is a β-dipeptide and a product of cyanophycin degradation by cyanophycinase^[1]^[2].

All Endogenous Metabolite Isoforms :

In Vitro

Beta-Asp-Arg serves as the substrate for Legionella longbeachae NSW150 dipeptidase Llo2535, whose hydrolysis of Beta-Asp-Arg supports the bacterium's nutrient utilization from cyanophycin^[1].
Beta-Asp-Arg forms multiple hydrogen bond interactions with Synechocystis sp. PCC6803 cyanophycinase in a covalent co-complex structure^[2].
Beta-Asp-Arg (200 μM) alone shows no measurable binding to inactive Synechocystis sp. PCC6803 cyanophycinase S132A, while the dimer (β-Asp-Arg)₂ (300 μM) binds with high affinity (K_d = 9.3 μM) and the trimer (β-Asp-Arg)₃ (200 μM) binds with lower affinity (K_d = 25.1 μM)^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
