Methylolanthanin

Name: Methylolanthanin
Brand: MedChemExpress
SKU: HY-187523
Availability: PreOrder

(Synonyms: para-MLL)

Methylolanthanin (para-MLL) is a natural small-molecule metallophore identified in the culture supernatant of Methylobacterium extorquens AM1. Methylolanthanin binds lanthanide metal ions such as La³⁺, Nd³⁺ and Lu³⁺. It is applicable to studies related to lanthanide metabolism, bacterial metallophores, metal homeostasis and methylotrophic metabolism.

In Vitro

Methylolanthanin (para-MLL) (10 μM; 15 min) forms insoluble complexes with La³⁺, Nd³⁺, Eu³⁺, and Lu³⁺ at pH 6.0, causing the complexes to precipitate from the solution^[1].
Methylolanthanin (18.75 μM) exhibits low iron (III)-binding affinity and only weak ability to compete with the CAS/HDTMA complex for Fe³⁺ at pH 6.0^[1].
Methylolanthanin forms the [MLL-H+Ln³⁺]²⁺ complex with La³⁺, Nd³⁺ and Lu³⁺^[2].
Methylolanthanin (50 nM) significantly increases the growth yield of M. extorquens AM1 ΔmxaF and ΔmxaFΔmll mutants under conditions of 2 μM or 50 nM NdCl₃^[2].
Methylolanthanin binds Eu³⁺ within the micromolar and nanomolar concentration ranges and forms detectable Eu³⁺-MLL particles, with a log K_SP of -12.07 for the precipitated complex^[3].

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.
