P2 protamines from human sperm are zinc-finger proteins with one Cys2/His2 motif

P1 (HP1) and P2 (HP2, HP3, HP4) protamines were isolated from human sperm nuclei in the reduced form and their interaction with zinc and cobalt was studied. One zinc atom per molecule of P2 protamines but not of P1 protamine was found. Absorption spectra of P2 protamines with cobalt were characteris...
