Product Description

Cy3-Labeled SpoVM Peptide contains the complete 26-amino-acid Bacillus subtilis SpoVM protein sequence MKFYTIKLPKFLGGIVRAMLGSFRKD with an added C-terminal cysteine used for Cy3 labeling.

SpoVM and Bacterial Sporulation

SpoVM is a remarkably small bacterial protein expressed during sporulation. It associates with the surface of the developing forespore and has become a model system for studying how short amphipathic peptides recognize membrane properties such as curvature and lipid organization.

The complete SpoVM sequence is publicly curated in UniProtKB as the Stage V sporulation protein M from Bacillus subtilis strain 168.

Cy3-Labeled SpoVM

The added terminal cysteine provides a site for maleimide-directed Cy3 attachment. A fluorescent SpoVM derivative can be useful for visualizing peptide localization, membrane association, and surface binding in bacterial or model-membrane experiments.

Scientific Background

Cy3-Labeled SpoVM Peptide is a 26-residue synthetic peptide with the sequence Met-Lys-Phe-Tyr-Thr-Ile-Lys-Leu-Pro-Lys-Phe-Leu-Gly-Gly-Ile-Val-Arg-Ala-Met-Leu-Gly-Ser-Phe-Arg-Lys-Asp. Cy3 provides a fluorescent label for optical detection. The sequence contains 4 Lys and 2 Arg residues, contributing cationic character; contains 4 aromatic residues that can contribute to hydrophobic or aromatic interactions; has a relatively high hydrophobic-residue fraction that can influence aqueous solubility and surface adsorption. These sequence-derived properties describe the reagent chemically; no specific receptor, enzyme, pathway, disease association, or biological activity is assigned without product-specific experimental evidence.

Research Applications
  • fluorescence-based detection
  • binding or localization assay development
  • LC-MS/HPLC analytical method development
  • sequence-specific assay controls
Experimental Notes

Sequence-derived chemical properties support reagent selection and experimental planning but do not establish biological function. Solubility, aggregation, adsorption, conjugation efficiency, and assay performance should be validated under the intended experimental conditions.
