Characterization of the enzymatic activity and physiological function of the lipid droplet-associated triacylglycerol lipase AtOBL1.
Mueller A.O., Ischebeck T.
Similar to seeds, pollen tubes contain lipid droplets that store triacylglycerol (TAG), but the fate of this TAG as well as the enzymes involved in its breakdown are unknown. Therefore, two potential TAG lipases from tobacco and Arabidopsis, NtOBL1 (Oil body lipase 1) and AtOBL1, were investigated ... >> More
Similar to seeds, pollen tubes contain lipid droplets that store triacylglycerol (TAG), but the fate of this TAG as well as the enzymes involved in its breakdown are unknown. Therefore, two potential TAG lipases from tobacco and Arabidopsis, NtOBL1 (Oil body lipase 1) and AtOBL1, were investigated, especially with respect to their importance for pollen tube growth. We expressed NtOBL1 and AtOBL1 as fluorescent fusion proteins to study their localization by confocal microscopy. Furthermore, we overexpressed AtOBL1 in Nicotiana benthamiana leaves to characterize it enzymatically. The obl1 mutant was studied in respect to its pollen tube growth in vivo and its seed germination. Both NtOBL1 and AtOBL1 localized to lipid droplets. AtOBL1 was abundant in pollen tubes and seedlings, and acted as a lipase on TAG, diacylglycerol and 1-monoacylglycerol at a pH optimum of 5.5. The obl1 mutant was hampered in pollen tube growth, whereas seedling establishment was not affected under optimal conditions, even though AtOBL1 accounted for a major lipase activity in seeds. TAG could be a direct precursor for the synthesis of membrane lipids in pollen tubes and proteins of the OBL family involved in the flux of acyl groups. << Less

Messenger RNAs expressed in intestine of adult but not baby rabbits. Isolation of cognate cDNAs and characterization of a novel brush border protein with esterase and phospholipase activity.

Using a subtractive hybridization method, we have cloned cDNAs corresponding to 10 different mRNAs which share the property of being expressed in the intestine of adult but not baby rabbits. Four could be identified as coding for previously known gene products (sucrase-isomaltase, a glutathione S-transferase, a cytochrome P450, and a long form of ferritin mRNA), while six code for previously unknown proteins. One clone, AdRab-B, codes for a protein of 1458 amino acids, including (i) a putative signal sequence at the NH2 terminus, (ii) four internal repeats, 308-346 amino acids in length, (iii) a hydrophobic stretch near the COOH terminus, which represents a potential membrane anchor, and (iv) a short hydrophilic stretch at the very COOH terminus. The corresponding protein was studied with the aid of antibodies prepared against polypeptides expressed from segments of the cDNA in Escherichia coli. The protein was shown to be proteolytically processed in the intestine (but not when expressed in COS cells) and to be targeted to the brush border membrane of the enterocytes. Finally, the protein was found to have esterase and phospholipase A/lysophospholipase activity. << Less
