The phrase "a common fold" is correct and usable in written English.
It can be used in contexts where you are referring to a shared or typical way of folding something, such as paper or fabric, or in a metaphorical sense to describe a commonality among a group.
Example: "In origami, a common fold is the valley fold, which is essential for creating many designs."
Alternatives: "a typical fold" or "a standard fold".
TheseSET proteins are based on a common fold that appears unique to this family.
It currently encompasses three protein families, SMP-like, BPI-like, and Takeout-like, which share a common fold.
The members of this enzyme superfamily display low levels of sequence identity while possessing a common fold and active site.
Despite immense diversity within the recognized substrates, all members of the family share a common fold that includes two domains that are separated by a conserved hinge.
Crotamine, therefore, belongs to a newly identified structural family presenting a common fold also found in β-defensin and antopleurine-B.
Our richly statistically supported findings show that complementary searches in both databases will increase the effectiveness of sequence-based searches in recognizing all homologues sharing a common fold.
In New York City, about 4,000 people are arrested each year for the crime of carrying a common folding knife.
The aim was to investigate whether the starting enzyme conformations of A1 and A2 would lead to different final tertiary structures or if they could converge to a common folding and loop axis orientation.
(2) α/β hydrolases do not have a common folding pathway.
While there is evidence that proteins sharing the same fold also share a common folding pathway [ 19, 20], this observation was based on a small set of proteins and therefore can not be generalized.
Similarly to the classical sequence alignment problem, the goal of the SAF problem is to find an alignment of several RNA strings, and in addition to find a common folding for the aligned segments of the strings.
