A long hydrophobic tunnel is proposed to function in the sequential binding of phytoene and the electron acceptor plastoquinone.
Expression of MT genes has been reported in a variety of plant tissues and has been proposed to function in metal homeostasis/detoxification, oxidative stress defense, salinity and carbonate stress, and development regulation (Sato and Bremner [1993]).
Several mechanisms were proposed to function in non-classical protein secretion.
Myosin Va has also been proposed to function in nuclear compartmentalization and transcription [47].
NuA4 is the only essential HAT complex in S.cerevisiae and has been proposed to function in DNA replication [58], [61].
The QKI isoforms have been proposed to function in alternative splicing in the myelin associated glycoprotein mRNA [16].
APPL proteins associate dynamically with endosomal membranes and are proposed to function in endosome-mediated signaling pathways linking the cell surface to the cell nucleus.
Bcd is localized in nuclei, and nuclei have been proposed to function in maintaining a stable Bcd gradient by contributing to the degradation of Bcd [8].
This pathway, which has only recently been elucidated in Rhodobacter sphaeroides, has been proposed to function in Methylobacterium [14], [15] based on earlier mutant studies [16], [17] as well as studies with recombinant enzymes [14], [15], [18], [19].
Since UNG2 is proposed to function in post-replicative repair and reported to colocalize with replication foci [50], we wondered whether the H2AX phosphorylation was occurring during S phase or G2.
All three strains showed elevated expression of the major facilitator family transporter (EF0082) proposed to function in import of phosphorylated sugars [42] and glycerol [43], which implies that such substrates might contribute to growth in urine.
