Type: | Repeat | Name: | Hexapeptide repeat |
Description: | A variety of bacterial transferases contain a repeat structure composed of tandem repeats of a [LIV]-G-X(4) hexapeptide, which, in the tertiary structure of LpxA (UDP N-acetylglucosamine acyltransferase) [], has been shown to form a left-handed parallel beta helix. A number of different transferase protein families contain this repeat, such as galactoside acetyltransferase-like proteins [], the gamma-class of carbonic anhydrases [], and tetrahydrodipicolinate-N-succinlytransferases (DapD), the latter containing an extra N-terminal 3-helical domain []. | Short Name: | Hexapep |
