Lipid-anchored membrane proteins that link to an isoprenoid chain via the sulfur atom of cysteine are called ________ proteins.
A)prenylated
B)sulfide-linked
C)cysteine-anchored
D)prostaglandins

Question

Quizplus · Accepted Answer

The question describes proteins that are linked to an isoprenoid chain via the sulfur atom of cysteine. This type of lipid modification is called prenylation. Therefore, the correct answer is A) prenylated proteins. Sulfide-linked and cysteine-anchored are not commonly used terms for describing this type of membrane protein, and prostaglandins are not typically attached to a sulfur atom in this manner.
