Structure of Hypothetical Protein LOC55471 Isoform 1
Dali shows a few proteins with similar structure to 1zkd. They are 2ex4 and 1im8 which shows the highest Z-value of 11.7 and 11.6 respectively. 2ex4 is a human methyltransferase with S-adenosylhomocysteine and 1im8 is found to be a methyltransferase with a bound S-adenosylhomocysteine from the crystal structure of YecO from Haemophilus influenzae (HI0319).

1zkd is an unknown protein, and by using proteins similar to it, the functions of this unknown protein can be predicted. With 2ex4 and 1im8 showed by Dali to be the most similar, other tools are used to determine the similarity. Combinatorial Extension Method is used. Below shows the sequence alignment and structure alignment of the unknown protein with the proteins obtained from dali:
