Though proteins can be stored with cosolvents such as salts and polyols to enhance their stability and activity for biological and biotechnological applications, however, the mechanisms for protein stability remain elusive. Generally, these cosolvents promote the shifting of protein conformations towards a more compact form and …
Angiotensin II from Angiotensinogen Angiotensin is a group of peptide hormones that contains mainly four types; I, II, III, and IV. However, the biologically active form is angiotensin II. All of these are produced from the single precursor protein angiotensinogen in different steps. Angiotensinogen is a …
Proteins associated with or embedded in a biological cell membrane are called membrane proteins. Membrane proteins are of two types. Integral Proteins Proteins that are embedded deeply in the plasma membrane are integral proteins. They are held inside the membrane by hydrophobic interaction. Integral proteins may …
