Can two different proteins have the same amino acid sequence?

Each type of protein has a unique sequence of amino acids, exactly the same from one molecule to the next. Many thousands of different proteins are known, each with its own particular amino acid sequence.

Can proteins formed by the different amino acid sequences can still perform the same function?

It is possible and known in certain cases. The sequence of amino acids in a protein defines the structure of the protein, however different amino acid sequence may also result in similar structure or conformation. Such as scenario is referred to as convergent evolution towards same function.

How is it possible for two proteins to have different functions?

Different proteins are made of different combinations of amino acids . The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a protein determines its function.

Do different amino acids have different functions?

There are 20 different amino acids that combine to create the impressive array of chemical versatility of proteins. The manner or sequence in which these amino acids combine to form a protein determines the 3-dimensional structure and function, which is unique to the particular protein.

Why two proteins with the same amino acid composition do not have the same primary structure?

No two proteins with different amino acid sequences (primary structure) have identical overall structure. The unique amino acid sequence of a protein is reflected in its unique folded structure. This structure, in turn, determines the protein’s function.

Can two proteins be the same?

It has been recognized for some time that two proteins can be similar to one another in structure despite a lack of any detectable sequence similarity and that this information can be used to assign function.

When two proteins contain the same type and number of amino acids but the order in which they link up is different the properties of the two proteins are the same?

Two proteins have the same number and type of amino acids but different tertiary structures. Explain why. The order of the amino acids (primary structure) in the two proteins may be different. This can result in ionic, hydrogen and disulphide bonds to form in different locations in each protein.

How can two proteins have the same number and type of amino acids but different tertiary structures?

The order of the amino acids (primary structure) in the two proteins may be different. This can result in ionic, hydrogen and disulphide bonds to form in different locations in each protein. Such differences may cause variations in the three dimensional structures of the proteins (tertiary structure).

How could one gene code for two proteins with different amino acids?

Scientists have long known that it’s possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA. Human genes typically contain several “exons,” or DNA sequences that code for amino acids, the building blocks of proteins.

What makes one kind of amino acid different from one another?

The side groups are what make each amino acid different from the others. These names refer to the way the side groups, sometimes called “R” groups, interact with the environment. Polar amino acids like to adjust themselves in a certain direction. Non-polar amino acids don’t really care what’s going on around them.
