Proteins by structure

spherical ("globe-like") protein; one of the common protein types (the others being fibrous, disordered and membrane proteins); somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins

protein type

various types of partially folded protein states found in mildly denaturing conditions (e.g. low pH, mild denaturant, or high temperature), collapsed with some native-like secondary structure and a dynamic tertiary structure
