EXHIBIT 99.1  Press Release

ORTHODONTIX AND PROTALIX ANNOUNCE MERGER AGREEMENT

     Miami, Florida and Carmiel, Israel --  August 22, 2006  -- Orthodontix,
Inc. (OTIX:OTC.BB), a publicly-held company located in Miami, Florida, and
Protalix Ltd., an Israeli biotechnology company, announced today that they
entered into a definitive merger agreement on August 21, 2006.  Under the
terms of the agreement, each ordinary share of Protalix will be converted
into approximately 594.5 shares of common stock of Orthodontix.   The merger
is subject to customary covenants and several conditions, and is expected to
close in the fourth quarter of 2006.  As a result of the merger, it is
expected that Orthodontix shareholders will receive approximately 0.84% of
Protalix on a fully diluted basis.  Simultaneously with the execution of the
merger agreement, a small group of investors, including Dr. Phillip Frost and
Glenn Halpryn who own in the aggregate a majority of the outstanding common
stock of Orthodontix, agreed to invest $15 million in Protalix pursuant to a
stock purchase agreement, in exchange for ordinary shares representing
approximately 14% of Protalix on a fully-diluted basis.  The investors will
also receive warrants to purchase an additional 5% of the ordinary shares of
Protalix.    The stock purchase is expected to close within a month and is
not subject to completion of the merger.

     "We are excited by the breadth of Protalix's unique plant cell culture
bioreactor platform, the quality of the management team and the prospects for
the company's products and technology, particularly its lead product for the
treatment of Gaucher Disease, which is progressing through the clinical
development process," stated Dr. Phillip Frost.  "Based upon its unique
capabilities to manufacture safe and efficacious recombinant proteins for a
number of therapeutic areas, we expect that Protalix will establish itself
over the coming years as an innovative leader in this area."

     Dr. David Aviezer, Protalix's CEO said: "We are privileged to have Dr.
Frost join us as a shareholder and board member.  We believe that this
investment, made by a top- tier industry leader, provides important
recognition to Protalix's technology and vision. We are confident that
Protalix's Board of Directors will highly benefit from the knowledge and
experience brought by Drs. Frost and Hsiao".

     Mr. Eli Hurvitz, Chairman of Protalix's Board of Directors said: "We are
very pleased with Dr. Frost joining Protalix's Board of Directors.  This
investment is an important milestone in Protalix's pathway to becoming a true
international biotech player.  We view this as an important sign of
confidence in Israeli biotechnology in general and in Protalix in particular.
We are looking forward to joining forces with Dr. Frost. "

     Protalix has developed and patented a unique plant cell culture platform
and bioreactor system that provides an efficient, easily scaleable and cost-
effective system for the expression of human therapeutic proteins. The
company's lead program is the development of Glucocerebrosidase, as a
proprietary enzyme replacement therapy for the treatment of Gaucher Disease,
a genetic metabolic disorder. The drug is slated to begin Phase III clinical
trials this fall.
                                      3

<PAGE>
     In addition to enzymes, Protalix has produced several other classes of
biological molecules, including antibodies, hormones, peptide-based
veterinary vaccines, and beta interferon, demonstrating that the technology
can be extended to these types of therapeutics.  Protalix intends to leverage
the unique benefits of its biotechnology platform to generate revenue by
providing large-scale protein and antibody production capacity to
pharmaceutical and biotechnology companies, thus providing a cost-effective
solution for an anticipated worldwide production capacity shortfall.
Protalix has also entered into strategic and licensing-based collaborations
with several biotechnology and pharmaceutical companies.

     The investment will bring additional expertise to an already prominent
Protalix Board of Directors.  Eli Hurvitz, the Chairman of Protalix is also
Chairman of the Board of Teva Pharmaceutical Industries Ltd., an Israeli
generic pharmaceutical company that had $6.5 billion in revenue in 2005.
Following the investment, Dr. Phillip Frost, Vice-Chairman of Teva, will
become a member of the Board of Directors of Protalix.  Dr. Jane Hsiao, who
was formerly Vice-Chairman of IVAX Corporation and who is one of the new
investors in Protalix, will also become a director of Protalix.  Dr. David
Aviezer, the CEO of Protalix, will  serve as the CEO of the merged company.

     Orthodontix, which has been seeking a business combination, will change
its name to Protalix Biotherapeutics, Inc. after the merger and intends to
apply for listing on a major stock exchange.
