microtubule

This protein has as its fundamental building blocks heterodimers made up of a- and b-subunits.

F-actin

This form of the protein forms microfilaments that are important in cell crawling.

a-keratin

This basic structural unit of this protein is a dimer of a-helices that wind around each other.

vitamin k

This vitamin is required for modification reactions that occur in the Gla domain of prothrombin.

vitamin c

This vitamin is indirectly required for modification reactions that occur in the protein collagen.
