PPL recombinant PPL protein is a protein that is the best in recombinant technology, which has important biological functions and application prospects. In this article, the basic information and functional structure of PPL recombinant proteins will be described in detail.
1. Basic information of PPL recombinant protein.
PPL protein, which stands for Pancreatic Procarboxypeptidase-Like (pancreatic lipeptidine-like precursor protein), is a member of the pancreatic protease family. PPL protein is mainly found in the pancreas and is an enzyme responsible for digesting proteins and has important physiological functions. Catalog No. PA1000-9473
PPL recombinant protein is a protein expressed and purified by genetic engineering technology in hosts such as Escherichia coli, with high purity and stability. Its gene sequence has been optimized and engineered to obtain efficient expression and high yield of protein in large-scale production.
PPL recombinant proteins have a wide range of applications in the fields of molecular biology, medicine and biotechnology, and can be used in protein structure research, drug discovery, bioengineering and other fields.
2. Functional structure of PPL recombinant protein.
PPL protein is a protein containing active sites, and its main function is to hydrolyze proteins into amino acids and small peptides in the intestine, and participate in the digestion and absorption of proteins. Its structure includes parts such as signal peptide, precursor peptide, active domain, and C-terminal domain.
1.Signal peptide: is the N-terminal part of the PPL protein and is responsible for guiding the protein into organelles such as the endoplasmic reticulum and Golgi apparatus during extracellular secretion. Signal peptides are cleaved off after protein synthesis to release mature proteins.
2.Precursor peptide: It is the main structural part of the PPL protein, containing the active site and other functional domains. The precursor peptide undergoes material transport and post-modification in the cell, and finally forms a mature PPL protein.
3.Active domain: It is the functional core of the PPL protein, responsible for the hydrolysis of peptide bonds in proteins, so that proteins are broken down into amino acids and small peptides. The structure and function of the active domain are closely related, and have an important impact on the activity and substrate binding of proteins.
4.C-terminal domain: is the C-terminal part of the PPL protein and is responsible for stabilizing and regulating the structure and function of the protein. There is an interaction between the C-terminal domain and other domains, which affects the biological processes such as substrate specificity and activity regulation of PPL protein.
In general, PPL recombinant protein, as an important protease, has a complex and precise functional structure and plays a key role in multiple biological processes.
In the future, the research and application of PPL recombinant proteins will be further expanded and deepened, providing new opportunities and challenges for the development of life sciences and medicine. It is hoped that the introduction of this article can provide readers with a deeper understanding and understanding of PPL protein.
