Summary
Prolidase enzyme activity is crucial for collagen turnover and tissue repair. While its role as a standalone biomarker is debated, evaluating prolidase levels with other markers aids disease diagnosis and treatment monitoring.
Area of Science:
- Biochemistry
- Enzymology
Background:
- Prolidase (proline dipeptidase) is a unique enzyme involved in degrading C-terminal proline or hydroxyproline dipeptides.
- Its critical role in cellular functions necessitates understanding its regulatory mechanisms and parameters.
Purpose of the Study:
- To review the in vivo functions of prolidase.
- To discuss the utility of prolidase activity levels in diagnosing and monitoring various diseases.
Main Methods:
- Literature review focusing on prolidase functions and clinical applications.
- Analysis of existing research on prolidase activity in physiological and pathological conditions.
Main Results:
- Prolidase is integral to collagen turnover, inflammation, fibrosis, and skeletal development.
- Its diagnostic value may be limited as a sole marker, suggesting combined use with other biochemical markers.
Conclusions:
- Prolidase activity is significant in multiple physiological and pathological processes.
- Evaluating prolidase levels alongside other serum markers is recommended for effective clinical assessment and treatment monitoring.

5.3K
The theory of catalytically perfect enzymes was first proposed by W.J. Albery and J. R. Knowles in 1976. These enzymes catalyze biochemical reactions at high-speed. Their catalytic efficiency values range from 108-109 M-1s-1. These enzymes are also called 'diffusion-controlled' as the only rate-limiting step in the catalysis is that of the substrate diffusion into the active site. Examples include triose phosphate isomerase, fumarase, and superoxide dismutase.

The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonulcease P, by Sid Altman’s laboratory. Both Cech and Altman received the Nobel Prize in chemistry in 1989 for their work on ribozymes.

11.5K
Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

3.0K
Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...

Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.
