Decoding PDI diversity: Insights into structure, domains, and functionality in sorghum.

Area of Science:

• Biochemistry
• Molecular Biology
• Plant Science

Background:

• Proteins require correct three-dimensional folding for cellular function.
• Protein Disulfide Isomerases (PDIs) are key chaperones that facilitate protein folding by catalyzing disulfide bond formation and rearrangement.
• PDIs belong to the thioredoxin (TRX) superfamily and possess conserved CXXC motifs essential for their redox activity.

Purpose of the Study:

• To investigate the largely unexplored diversity of Protein Disulfide Isomerase (PDI) family members in sorghum (SbPDI).
• To characterize the domain architecture, three-dimensional structure, and potential functionality of SbPDI members.
• To provide insights into the structural and functional variations within the sorghum PDI family.

Main Methods:

• In silico identification and characterization of PDI family members in sorghum.
• Analysis of domain order and architecture.
• Prediction and exploration of three-dimensional protein structures.
• Assessment of potential protein functionality based on structural and domain analysis.

Main Results:

• Identification of a diverse range of PDI family members in sorghum with variations in domain composition and arrangement.
• Characterization of distinct domain architectures and predicted three-dimensional structures for SbPDI members.
• Insights into the potential functional roles and evolutionary adaptations of sorghum PDIs.

Conclusions:

• Sorghum PDI family exhibits significant diversity in structure and domain organization.
• Understanding SbPDI diversity is crucial for elucidating their specific roles in plant cellular processes.
• This study lays the groundwork for further functional validation of sorghum PDIs.
