The metabolism of Archaea, the third domain of life, resembles in its complexity those of
Bacteria and lower Eukarya. However, this metabolic complexity in Archaea is accompanied …

Three-dimensional structures have been elucidated for very few integral membrane
proteins. Computer methods can be used as guides for estimation of solute transport protein …

Kinases that catalyze phosphorylation of sugars, called here sugar kinases, can be divided
into at least three distinct nonhomologous families. The first is the hexokinase family, which …

Salt stress is a major environmental factor influencing plant growth and development. To
identify salt tolerance determinants, a genetic screen for salt overly sensitive (sos) mutants …

Summary Phytic acid, myo‐inositol‐1, 2, 3, 4, 5, 6‐hexakisphosphate or Ins P6, is the most
abundant myo‐inositol phosphate in plant cells, but its biosynthesis is poorly understood …

Lactose utilization is the primary function of lactic acid bacteria used in industrial dairy
fermentations. The mechanism by which lactose is transported determines largely the …

Background: D-ribose must be phosphorylated at O5′ before it can be used in either
anabolism or catabolism. This reaction is catalysed by ribokinase and requires the presence …

Purple photosynthetic bacteria exhibit great diversity in the metabolism of simple carbon
compounds. In this chapter, the reactions and metabolic schemes that the organisms …

Escherichia coli was found to grow on fructoselysine as an energetic substrate at a rate of
about one-third of that observed with glucose. Extracts of cells grown on fructoselysine …

ABSTRACT pdxK encodes a pyridoxine (PN)/pyridoxal (PL)/pyridoxamine (PM) kinase
thought to function in the salvage pathway of pyridoxal 5′-phosphate (PLP) coenzyme …
