delete all characters in line after certain string

Hi I have the following file:

>seq0 id345
FQTWEEFSRAAEKLYLADPMKVRVVLKYRHVDGNLCIKVTDDLVCLVYRTDQAQDVKKIEKF
>seq1 id1045
KYRTWEEFTRAAEKLYQADPMKVRVVLKYRHCDGNLCIKVTDDVVCLLYRTDQAQDVKKIEKFHSQLMRLME

and I am trying to remove any character after the > so i get:

>
FQTWEEFSRAAEKLYLADPMKVRVVLKYRHVDGNLCIKVTDDLVCLVYRTDQAQDVKKIEKF
>
KYRTWEEFTRAAEKLYQADPMKVRVVLKYRHCDGNLCIKVTDDVVCLLYRTDQAQDVKKIEKFHSQLMRLME

I have almost got this using:

sed -e 's/>.*//'

however this also deletes the > symbols leaving me with:

FQTWEEFSRAAEKLYLADPMKVRVVLKYRHVDGNLCIKVTDDLVCLVYRTDQAQDVKKIEKF

KYRTWEEFTRAAEKLYQADPMKVRVVLKYRHCDGNLCIKVTDDVVCLLYRTDQAQDVKKIEKFHSQLMRLME

how do i keep the > characters?

Thanks.

The simplest fix would be:

sed 's/>.*/>/'

A re-usable solution for more complicated cases (using a capturing group):

sed -r 's/(>).*/\1/'
