5.4.2.2 phosphoglucomutase (alpha-D-glucose-1,6-bisphosphate-dependent)IUBMB Comments
Maximum activity is only obtained in the presence of alpha-D-glucose 1,6-bisphosphate. This bisphosphate is an intermediate in the reaction, being formed by transfer of a phosphate residue from the enzyme to the substrate, but the dissociation of bisphosphate from the enzyme complex is much slower than the overall isomerization. The enzyme also catalyses (more slowly) the interconversion of 1-phosphate and 6-phosphate isomers of many other alpha-D-hexoses, and the interconversion of alpha-D-ribose 1-phosphate and 5-phosphate. cf. EC 5.4.2.5, phosphoglucomutase (glucose-cofactor).

alpha-D-glucose 1-phosphate = D-glucose 6-phosphate
in the forward reaction a phosphate from the enzyme is transferred to C-6 of glucose 1-phosphate which results in a dephosphoenzyme intermediate. In the second step phosphate from the C-1 of glucose is transferred to the enzyme for its regeneration. The reverse reaction proceeds via a similar mechanism

alpha-D-glucose 1-phosphate = D-glucose 6-phosphate
acid-base catalysis mechanism, key role for conformational change in its multistep reaction, which requires a dramatic 180 degree reorientation of the intermediate within the active site. Modeling shows that increased enzyme flexibility facilitates the reorientation of the reaction intermediate, coupling changes in structural dynamics with the unique catalytic mechanism of this enzyme

it is unclear whether either glucose or mannose phosphate represents the cellular substrate for SsoPHM. The Km values for rSsoPHM toward glucose 6-phosphate and mannose 6-phosphate are in the low millimolar range, significantly higher than that expected for a physiological substrate. Since the protein encoded by sso0207 is the only identifiable phosphohexomutase in the Sulfolbus solfataricus P2 genome, SsoPHM provides the only recognizable avenue for interconverting glucose 6-phosphate and glucose 1-phosphate during glycogen synthesis and breakdown

malfunction
-
targeted deletion of pgmA in Yersinia pestis strain KIM5 results in loss of autoaggregation, the deletion mutant displays more than 1000fold increased sensitivity to polymyxin B compared to the parental strain
malfunction
the pgm deletion mutant has impaired growth in vitro, is deficient in the ability to utilize alpha-D-galactose as a carbon source and displays reduced O-antigen polymer length
malfunction
-
whereas pgm2 and pgm3 single mutants are undistinguishable from the wild type, loss of both PGM2 and PGM3 severely impairs male and female gametophyte function. Double mutant pollen completes development but fails to germinate, double mutant ovules also develop normally, but approximately half remain unfertilized 2 d after pollination
malfunction
-
only mutants with a deletion of PGM3, not of PGM1 or PGM2, hyperaccumulate ribose-1-phosphate
malfunction
-
enzyme depletion is associated with declined cellular glycogen content and decreased rates of glycogenolysis and glycogenesis. Furthermore, enzyme depletion suppresses cell proliferation under long-term repetitive glucose depletion
malfunction
-
complete enzyme loss results in dwarf growth, prematurely die off, and inability to develop a functional inflorescence
malfunction
-
an enzyme-deficient mutant shows significantly reduced survival in embryonic trophoblast cells and in mice, and induces high protective immunity in BALB/c mice. Moreover, the mutant elicits an anti-Brucella-specific immunoglobulin G response and induces the secretion of gamma interferon and interleukin-2

physiological function
-
PgmA is required for efficient autoaggregation in Yersinia pestis and plays an important role in antimicrobial peptide resistance
physiological function
Pgm is required by Salmonella enterica serovar Typhimurium for O-antigen production, resistance to antimicrobial peptides, and in vivo fitness
physiological function
-
overexpression of pgm gene has no significant effect on UDP-glucose and UDP-galactose levels and increased alpha-Pgm activity does not significantly change the lactate production
physiological function
-
pollen germination requires cytosolic PGM activity
physiological function
-
Unlike the majority of alpha-phosphoglucomutases, the described enzyme of 252 residues with alpha-phosphoglucomutase activity, is related to eukaryotic phosphomannomutases and belongs to HAD-superfamily hydrolase, subfamily IIB.
physiological function
