Abstract
The present invention relates to an organism, a tissue, a cell or an organelle expressing enzymes which allow the conversion of 2-phosphoglycolate (2-PG; also known as glycolate 2-phosphate,) into an intermediate compound of the Calvin-Benson-Bassham Cycle (CBBC) without releasing CO2. The organism, tissue, cell or organelle of the invention may be genetically engineered, transgenic and/or transplastomic so as to express at least one enzyme which is involved in this conversion. The present invention further relates to an organism, tissue, cell or organelle which comprises/expresses at least one enzyme which is involved in this conversion. The present invention further relates to a method for producing an organism, tissue, cell or organelle of the invention. The present invention further relates to a method of enzymatically converting 2-PG into an intermediate compound of the CBBC without releasing CO2. The present invention further relates to the use of an organism, tissue, cell or organelle of the invention for enzymatically converting 2-PG into an intermediate compound of the CBBC without releasing CO2.
