0-107 |
Sentence |
denotes |
YMR313c/TGL3 encodes a novel triacylglycerol lipase located in lipid particles of Saccharomyces cerevisiae. |
| T2 |
108-202 |
Sentence |
denotes |
Previous work from our laboratory (Athenstaedt, K., Zweytick, D., Jandrositz, A., Kohlwein, S. |

Sentence |
denotes |
D., and Daum, G. (1999) J. |

Sentence |
denotes |
Bacteriol. |
| T5 |
241-445 |
Sentence |
denotes |
181, 6441-6448) showed that the gene product of YMR313c (named Tgl3p) is a component of yeast lipid particles, and deletion of this gene led to an increase in the cellular level of triacylglycerols (TAG). |
| T6 |
446-537 |
Sentence |
denotes |
These observations suggested that TGL3 may encode a TAG lipase of Saccharomyces cerevisiae. |
| T7 |
538-764 |
Sentence |
denotes |
Here we demonstrate by cell fractionation and by microscopic inspection of a strain bearing a Tgl3p-GFP hybrid that this polypeptide is highly enriched in the lipid particle fraction but virtually absent from other organelles. |
| T8 |
765-1001 |
Sentence |
denotes |
The entire TAG lipase activity of lipid particles is attributed to Tgl3p, because the activity in this organelle is completely absent in a Deltatgl3 deletion mutant, whereas it is significantly enhanced in a strain overexpressing Tgl3p. |
| T9 |
1002-1149 |
Sentence |
denotes |
A His6-tagged Tgl3p hybrid purified close to homogeneity from a yeast strain overexpressing this fusion protein exhibited high TAG lipase activity. |
| T10 |
1150-1339 |
Sentence |
denotes |
Most importantly, experiments in vivo using the fatty acid synthesis inhibitor cerulenin demonstrated that deletion of TGL3 resulted in a decreased mobilization of TAG from lipid particles. |
| T11 |
1340-1482 |
Sentence |
denotes |
The amino acid sequence deduced from the open reading frame YMR313c contains the consensus sequence motif GXSXG typical for lipolytic enzymes. |
| T12 |
1483-1572 |
Sentence |
denotes |
Otherwise, Tgl3p has no significant sequence homology to other lipases identified so far. |
| T13 |
1573-1699 |
Sentence |
denotes |
In summary, our data identified Tgl3p as a novel yeast TAG lipase at the molecular level and by function in vivo and in vitro. |
