Proteomics unveils chemical modifications on protein side chains in raw breast meat of broilers (Gallus gallus) affected with growth-related myopathies.

ABSTRACT:

Objective

This study aimed to investigate how growth-related myopathies influenced chemical modifications formed on amino acid residues of chicken breast proteins.

Methods

Breasts (pectoralis major) of commercial broilers (Gallus gallus) were classified into "normal", White Striping (WS)" and "White Striping + Wooden Breast (WS+WB)" groups (n = 9 per group). The meat was subjected to proteomic analysis using a liquid chromatography-tandem mass spectrometry. Differences in abundance of modified sites, including methylated lysine (Lys) and arginine, acetsylated Lys, and oxidized methionine (Met), due to the growth-related myopathies were identified (false discovery rate [FDR]<0.05). Biological functions of the proteins were analyzed.

Results

Proteomics revealed 185, 105
