Implication

Does not support direct translation to vertebrate troponin diagnostics; leaves open the extent of functional domain conservation across species.

Key Points

The aim is to determine the complete amino acid sequence of crayfish troponin I and analyze its similarities with vertebrate counterparts.
Determined the amino acid sequence of crayfish tail muscle troponin I
Analyzed sequence identity with vertebrate troponin I
Identified conserved and unique regions in the protein structure.
Crayfish troponin I has 201 amino acid residues and a molecular weight of 23,547.
The sequence identity with vertebrate troponin I is low (20-25%), while within vertebrates it reaches 60-82%.
Features unique trimethyllysine residues and specific calcium binding sites, indicating evolutionary divergence.
