An aldehyde dehydrogenase was detected in crude cell extracts of Escherichia coli DH5alpha. Growth studies indicated that the aldehyde dehydrogenase activity was growth phase dependent and increased in cells grown with ethanol. The N-terminal amino acid sequence of the purified enzyme identified the latter as an aldehyde dehydrogenase encoded by aldB, which was thought to play a role in the rem...
OBJECTIVE To analyze the expression of hypoxia-inducible factors (hypoxia-inducible factor 1A and hypoxia-inducible factor 2A) and aldehyde dehydrogenase proteins in patients with locally advanced breast carcinoma who were subjected to neoadjuvant chemotherapy. METHODS We included 90 patients with histologically confirmed stage II and III breast carcinoma who were treated with neoadjuvant che...
The crystal structure of 5-methyl-salicyl-aldehyde (5-MSA; systematic name 2-hy-droxy-5-methyl-benzaldehyde), C8H8O2, was discovered to be a textbook example of the drastic structural changes caused by just a few weak C-H⋯O inter-actions due to the additional methyl-ation of the aromatic ring compared to salicyl-aldehyde SA. This weak inter-molecular hydrogen bonding is observed between aromati...
