CC -!- FUNCTION: Bifunctional enzyme which catalyzes the transfer of glucose
CC from UDP-alpha-D-glucose to glucose-6-phosphate to form trehalose-6-
CC phosphate (Tre6P) and removes the phosphate from Tre6P to produce free
CC trehalose. {ECO:0000269|PubMed:23626675}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glucose 6-phosphate + UDP-alpha-D-glucose = alpha,alpha-
CC trehalose 6-phosphate + H(+) + UDP; Xref=Rhea:RHEA:18889,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:58223, ChEBI:CHEBI:58429,
CC ChEBI:CHEBI:58885, ChEBI:CHEBI:61548; EC=2.4.1.15;
CC Evidence={ECO:0000269|PubMed:23626675};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha,alpha-trehalose 6-phosphate + H2O = alpha,alpha-
CC trehalose + phosphate; Xref=Rhea:RHEA:23420, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:16551, ChEBI:CHEBI:43474, ChEBI:CHEBI:58429; EC=3.1.3.12;
CC Evidence={ECO:0000269|PubMed:23626675};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:P31678, ECO:0000269|PubMed:23626675};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Temperature dependence:
CC Active at 80 degrees Celsius. {ECO:0000269|PubMed:23626675};
CC -!- PATHWAY: Glycan biosynthesis; trehalose biosynthesis.
CC {ECO:0000269|PubMed:23626675}.
CC -!- SUBUNIT: May interact with the putative glycosyltransferase (GT)
CC TTX_1305. TTX_1305 is required for the trehalose-6-phosphate synthase
CC activity of tpsp. {ECO:0000269|PubMed:23626675}.
CC -!- MISCELLANEOUS: Part of an operon with putative glycosyltransferase
CC TTX_1305 and putative membrane protein TTX_1304.1.
CC -!- SIMILARITY: In the N-terminal section; belongs to the
CC glycosyltransferase 20 family. {ECO:0000255}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the trehalose
CC phosphatase family. {ECO:0000255}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAF18468.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
