Result from DALI shows proteins that are similar to the 1zkd. They are 2ex4 and 1im8. These 2 proteins matches 1zkd the most according to DALI. The pictures below shows the structures of the proteins related comparing to 1zkd.

1zkd
2ex4
1im8
1im8

















With these informations we can now look into the proteins that is similar to 1zkd and predict the functions. 1im8 is found to be a methyltransferase with a bound S-adenosylhomocysteine from the crystal structure of YecO from Haemophilus influenzae (HI0319). 2ex4is a human methyltransferase with S-adenosylhomocysteine.
