Ac-SDKP

Acetyl-Ser-Asp-Lys-Pro

4 residues · 488 Da · 67 atoms

Four residues with an acetyl cap, which is drawn. Released naturally from thymosin beta-4, the full form of which is also in this library.

Antiflammin-2

9 residues · 1084 Da · 75 atoms

Nine residues taken from a stretch of uteroglobin. One of the shorter sequences in this library to have been studied on its own rather than as part of its parent protein.

Bivalirudin

20 residues · 2180 Da · 155 atoms

Twenty residues opening with D-phenylalanine, whose side chain is mirrored here, then four glycines forming a deliberately floppy linker between two binding ends. Strongly acidic through the second half.

BPC-157

Body Protection Compound 157

15 residues · 1420 Da · 100 atoms

A 15-residue partial sequence derived from a protein found in human gastric juice. Studied in preclinical models for effects on connective tissue and the gastrointestinal lining. The proline-rich middle is why the backbone is modelled in a polyproline-II conformation.

Larazotide

Octapeptide of the tight junction

8 residues · 726 Da · 106 atoms

Eight residues, mostly small and aliphatic, with a single proline. Studied for its effect on intestinal tight junctions.

Osteocalcin

49 residues · 5800 Da · 411 atoms

Forty-nine residues, the most abundant non-collagen protein in bone. The natural form carries three modified glutamates that bind calcium; those modifications are not drawn, so this is the unmodified chain.

Osteogenic growth peptide

14 residues · 1524 Da · 108 atoms

Fourteen residues identical to the tail of histone H4. The library already holds buforin, which comes from histone H2A, so two different histones are represented.

TB-500

Thymosin beta-4 fragment (17-23)

7 residues · 889 Da · 126 atoms

The seven-residue actin-binding stretch of thymosin beta-4, N-terminally acetylated. Studied alongside BPC-157 in tissue-repair research.

In our catalogue

Thymosin beta-4

All 43 residues, acetylated

43 residues · 4964 Da · 347 atoms

The full protein that TB-500 is a seven-residue fragment of, with the acetyl cap it naturally carries. Seeing both in this library shows how small the active fragment is against the whole.
