What is a helix-loop-helix motif? - Answers A common protein motif found in c-myc.
What is a beta hairpin? - Answers A common protein motif.
What is a Greek key motif? - Answers A common protein motif.
What is a zinc-finger motif? - Answers A common protein motif.
What characterizes antiparallel beta sheets? - Answers Beta strands run in opposite directions.
What is the globin fold domain? - Answers An all-alpha protein domain with 8 alpha helices.
What is a bromodomain? - Answers An all-alpha protein domain with 4 alpha helices.
What is the SH3 domain? - Answers An all-beta protein domain that forms a 5-strand beta barrel.
What is a beta barrel structure? - Answers An all-beta protein domain, such as the 18-strand
porin.
What is a 7-bladed beta-propeller structure? - Answers A structure found in the WD40 domain of
Tup1.
What is the antigen-binding domain of an antibody? - Answers It consists of ten immunoglobulin
domains.
What is the significance of intrinsically disordered proteins (IDPs)? - Answers They can take on
many structures and are fairly common.
What is the main curator of protein classification? - Answers Pfam.
What does SCOP stand for? - Answers Structural Classification of Proteins.
What is CATH in protein classification? - Answers Class/Architecture/Topology/Homology.
What is the Protein Data Bank (PDB)? - Answers A repository for protein structures.
What does MMDB provide? - Answers Access to PDB within NCBI.
What is a characteristic feature of restriction enzymes? - Answers Restriction enzymes are
palindromic, meaning they recognize the same sequence of nucleotides when read in both
directions.
If given 3 bases of a 6-base recognition site, how can you complete it? - Answers You can fill in
the remaining 3 bases by knowing that the recognition site is palindromic, allowing you to mirror
the first 3 bases.
