This is likely to be due to the presence of brominated indole precursors of Tyrian purple in homogenates from these glands, which show strong inhibitory activity against a range of Gram positive and Gram negative bacteria (Benkendorff et al.
Furthermore, tissues associated with particular secondary metabolites, such as Tyrian purple precursors, are likely to support distinct chemical environments.
This is consistent with previous findings of higher concentrations of methane thiol containing intermediate precursors of Tyrian purple in female glands compared with oxidized products in the males (Westley & Benkendorff 2008).
Enzyme activity associated with the metabolism of sugar substrates, such as L-rhamnose, D-melibiose, and L-arabinose was also less common in the Tyrian purple producing biosynthetic organs, particularly in male D.
could be providing some of the basic building blocks for Tyrian purple precursor synthesis, which may be acquired opportunistically and stored within the biosynthetic organs.
For this reason the snails should never be removed from the rocks, and dyeing materials with Tyrian purple should only, in exceptional cases, be permitted to the indigenous people to allow the survival of an tradition.
Possibly the first written report about the traditional use of Tyrian purple in Central America comes from the preacher Thomas Gage of England.
Unfortunately, Thomas Gage did not describe in more detail which other gastropods were exploited for their Tyrian purple.
In 1744, during cartographic research, the Spanish scientists Jorge and Antonio Ulloa observed at Santa Elena close to Guayaquil in Ecuador, and also in Nicoya, the production and use of Tyrian purple from marine snails.
The color most valued is the Tyrian purple, obtained from the murex shellfish, which is found on the Pacific coast of Nicaragua.
In antiquity and in medieval times, Tyrian purple was used in special manuscripts ("Purple codices") as a priming color of parchments, in addition, in a pre-Columbian Mixtec (Codex Nuttall) manuscript, Tyrian purple was applied from an as-yet undetermined snarl source, however not as priming color, hut as paint.
