bactenecin

These are published properties of the molecule, given for identification. Values we cannot confirm are omitted rather than estimated. What these terms mean.

What this compound is

Twelve residues with cysteines at three and eleven joined by a disulfide, closing a loop with a single residue hanging off each end. The smallest cyclic antimicrobial peptide from cattle.

Sequence

Bactenecin amino-acid sequence in one-letter code, numbered by residue position
1RLCRIVVIRV CR
Three-letter code
Arg-Leu-Cys-Arg-Ile-Val-Val-Ile-Arg-Val-Cys-Arg

The one-letter code gives the amino-acid backbone. Terminal modifications, where a compound carries them, are accounted for in the molecular weight above but are not visible in the letters.

Residue composition

Counted directly from the sequence above. Bactenecin is built from 5 of the twenty standard amino acids across 12 positions.

Side-chain classes follow the standard grouping of the twenty proteinogenic amino acids. Composition is arithmetic over the published sequence and says nothing about how the molecule behaves.
