E, F	PF00906	Hepatitis core antigen (Hepatitis_core)	Hepatitis core antigen	The core antigen of hepatitis viruses possesses a carboxyl terminus rich in arginine. On this basis it was predicted that the core antigen would bind DNA [1]. There is some experimental evidence to support this [2].	Domain
E, F	PF08290	Hepatitis core protein, putative zinc finger (Hep_core_N)	Hepatitis core protein, putative zinc finger	This short region is found at the N-terminus of some hepatitis core proteins. Its conservation of four cys and his suggests a zinc binding domain.	Domain
