Peptide Sequence: 6C-AC-Asp-Gly-Gly-Leu-Ala-G-NH2

This is a synthetically modified peptide sequence with the following structural features:

• 6C-AC:   This indicates that the   N-terminus   of the peptide is conjugated with a   6-Carboxyfluorescein   molecule. Fluorescein is a commonly used   fluorophore   that emits bright green fluorescence when excited by ultraviolet or blue light. This label allows the peptide to be used for tracking, detection, and imaging applications, such as fluorescence microscopy, flow cytometry, or fluorescence polarization assays.
   

• Asp-Gly-Gly-Leu-Ala-G:   This is the core amino acid sequence of the peptide, consisting of Aspartic acid (Asp), Glycine (Gly), Glycine (Gly), Leucine (Leu), Alanine (Ala), and Glycine (Gly). This sequence may mimic a functional region of a specific protein, but its exact biological function would depend on the context of its design. The motif " Gly-Gly-Leu " is often found in some protease substrates or binding domains.

• NH2:   This indicates that the   C-terminus   of the peptide is   amidated . This is a common modification that converts the native carboxylic acid group (-COOH) into an amide group (-CONH2). Amidation can enhance the peptide's stability and bioavailability by protecting it from degradation by certain carboxypeptidases and is sometimes crucial for maintaining its full biological activity.
