HB	Hevea brasiliensis	cis-1,4-polyisoprene	HRBP	LC057267	CPTL	cpt_cptl	A_direct_experiment	HRBP was reported as a helper subunit in the HRT1 rubber-particle complex.	Complex-support evidence, not a stand-alone catalytic claim.	Identification and reconstitution of the rubber biosynthetic machinery on rubber particles from Hevea brasiliensis	10.7554/eLife.19022	27790974	BAB71776.2;AB061234.3;LC057267	https://doi.org/10.7554/eLife.19022	Rubber particles
HB	Hevea brasiliensis	cis-1,4-polyisoprene	HRT1	BAB71776.2;AB061234.3	CPT	cpt_cptl	A_direct_experiment	HRT1 showed in-vitro rubber-transferase activity on detergent-washed rubber particles, with higher activity for the HRT1-REF-HRBP complex.	Direct evidence in Hevea rubber particles; not direct validation in rubber dandelion.

HB	Hevea brasiliensis	cis-1,4-polyisoprene	HRT2	Q8W3U4;AB064661.2	CPT	cpt_cptl	A_enzyme_experiment	HRT2 is retained as a cis-prenyltransferase and latex-expression reference.	Do not claim direct reconstitution of high-molecular-weight natural rubber by HRT2 alone.
