What is the largest protein structure?
Titin
Titin is the largest protein chain in your body, with more than 34,000 amino acids. This titanic protein acts like a big rubber band in our muscles. It is attached at one end to the Z-disk (shown here at the top in blue), which organizes the thin actin filaments.
What is the smallest human protein?
The smallest human protein is 44 amino acids but it could be an abortive translation from the 5′ UTR of another mRNA. The smallest functional polypeptide is glutathione with only three amino acids. BTW, proline is technically not even an amino acid much less a polypeptide.
Where is titin found in the human body?
Titin is a huge, 4.2 MDa, filamentous protein located in the sarcomere of striated muscle. Extending from its N-terminus anchored in the Z-disc to its C-terminus bound to thick filaments in the M-band, titin is largely responsible for the passive stiffness of the myocardium exhibited during diastolic filling.
How big is a titin molecule?
1µm
Titin, a polypeptide chain protein that is greater than 1µm in length and 3-4 nm in width. The protein molecule has a molecular weight of up to approximately 4 Mda. Titin is a multi-domain structure that which is found to be composed of two types of domains similar to immunoglobulin (Ig) and fibronectin.
What is the largest enzyme in human body?
The largest Enzyme in the human body is Titin. The length of titin enzyme is about 27,000 to 35,000 amino acids. Titin is referred to as Connection, which is encoded by TTN Genes. TTN Genes provides instructions for making very large proteins.
Which protein is abundant in human body?
collagen
Type I collagen is the most abundant protein in human body. The protein turns over slowly and its replacement synthesis is low.
Which is the largest gene in human body?
DMD
DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle.
What is the biggest human enzyme?
With its length of ~27,000 to ~35,000 amino acids (depending on the splice isoform), titin is the largest known protein. Furthermore, the gene for titin contains the largest number of exons (363) discovered in any single gene, as well as the longest single exon (17,106 bp).
Which is the fastest enzyme?
Carbonic anhydrase
The fastest enzyme is Carbonic anhydrase.
Which is the smallest and largest enzyme?
Peroxidose is the smallest enzyme and catalase is the largest enzyme.
What is the most common protein?
RuBisCO
Protein Basics A protein is a polypeptide, a molecular chain of amino acids. Polypeptides are, indeed, the building blocks of your body. And, the most abundant protein in your body is collagen. However, the world’s most abundant protein is RuBisCO, an enzyme that catalyzes the first step in carbon fixation.
