How to break on assembly instruction at a given address in gdb?

Question

0x0000000000400448 <main+0>:    push   %rbp
0x0000000000400449 <main+1>:    mov    %rsp,%rbp
0x000000000040044c <main+4>:    mov    $0x6,%eax
0x0000000000400451 <main+9>:    leaveq 
0x0000000000400452 <main+10>:   retq   

I tried:

breaki 0x0000000000400448

but it seems that there not such command.

Does gdb have such a feature?
