Nucleotide sequence of the Escherichia coli gap gene. Different evolutionary behavior of the NAD+-binding domain and of the catalytic domain of D-glyceraldehyde-3-phosphate dehydrogenase

Eur J Biochem. 1985 Jul 1;150(1):61-6. doi: 10.1111/j.1432-1033.1985.tb08988.x.

Abstract

A 1523-base-pair DNA fragment, spanning the gap gene from Escherichia coli, has been sequenced. It contains an open-reading frame whose length (330 amino acids) is in agreement with D-glyceraldehyde-3-phosphate dehydrogenase (GAPDH) molecular mass. This coding sequence is preceded by a Shine-Dalgarno complementary sequence and by two overlapping promoter-like structures. The codon usage within gap is consistent with that expected for a gene which is strongly expressed. The amino acid sequence of the E. coli GAPDH, deduced from the DNA sequence, contains all the amino acids postulated to play a functional role in GAPDH. Comparison of the E. coli enzyme with enzymes from other species reveals different evolutionary behaviour of the NAD+-binding domain and of the catalytic domain of GAPDH. The E. coli enzyme is found to be more similar to eucaryotic enzymes than to enzymes from thermophilic bacteria. This observation is discussed in terms of adaptation to growth at high temperature.
